A Brief History of Hearing Aids

Approximately 35 million Americans have some degree of hearing loss. In perspective, very few of them are prescribed a hearing aid. They can be quite costly, but their advantages are unparalleled and well worth it. On average, a hearing aid costs about $1500. They have come a long way from the primitive ear trumpets of 200 years ago. As a result of research over the years as well as growth in technology, these devices now come in a variety of shapes, sizes, and even colors. Plus, they only weigh a few ounces, providing an unmatched versatility to the user. They used to weigh tens of pounds! With connections to Bluetooth and filtering capabilities inherent in today’s models, there has been quite an evolution in terms of these devices.

On the Ear

It wasn’t till the late 1930s that hearing aids that could be worn on the ear with relative comfort got popular. These devices were made by a Chicago electronics manufacturer, featuring a thin wire connected to an earpiece and receiver. A battery pack which attached to the user’s leg made it hard to get around easily, though. More compact models emerged during World War II for more reliable service to the user thanks to the invention of printed circuit boards.

Precursors to Hearing Aids

Ear trumpets were crafted for the very wealthy, such as the Reynolds Trumpet, personally made for Joshua Reynolds, a famous painter of his time. The ear trumpet is a horn-shaped instrument that is designed to direct sound into the inner ear. It was invented back in the 17th century, which were beneficial only to those who suffered from a partial hearing impairment. These were large, cumbersome devices that only served to amplify sound within the immediate environment. Just think of an old phonograph with the conical sphere and you’ll get a good mental picture of what these resembled. As the 18th century approached, they came even further.

How can Phones Improve Hearing?

When the 19th century came about, electrical technologies emerged spurred on by the invention of the telephone by Alexander Graham Bell in 1876. This invention was a catalyst for advancement leading to electrical transmission of speech. Thomas Edison was inspired by this invention and came up with the carbon transmitter for the telephone in 1878. This was designed to boost the basics of the telephone as well as the electrical signal to improve hearing. The 17th and 18th centuries brought with them devices that offered only limited amplification qualities.

Modern Models

Behind-the-ear models, invented in 1964 by Zenith Radio, boasted digital signal-processing chips. Then along came hybrid analog-digital models and then fully digital models by 1996. By the year 2000, programmable hearing aids were on the scene that gave users increased flexibility, customization and comfort. Today, most — about 90 percent — of all hearing aids are digital in nature.

Vacuum Tubes Were Revolutionary Yet Cumbersome

Vacuum tubes, put out by Western Electric Co., came next in New York City in 1920. Manufactures built upon the technology that came from Lee De Forest’s finding of the three-component tube years earlier. They offered not only better amplification but also better frequency. However, they were huge and impractical. They got to the size of a small box eventually, but they were still quite inconvenient.
Today’s hearing aids are light years ahead in terms of size, weight, functionality and adaptability.

10 Things You Didn’t Know About Hearing Aids

Hearing aids have went through a large number of iterations in their 200-plus year history. The technology that is implemented in hearing aids has historically been developed by means of a devoted scientist who is either affected by hearing loss or has a friend or family member affected by hearing loss. As an example, Alexander Graham Bell’s mother had substantial hearing loss and his wife was deaf.

Here are 10 other little-known facts about hearing aids:

1. Hearing aids can be synced up with wireless devices through state of the art technology like Bluetooth, so users are able to enjoy direct signals from their smart phone, MP3 player, TV, and other gadgets.

2. Hearing aids are not one size fits all – in fact, they can and should be programmable. This means they have the capability to recall the most comfortable settings for the user, often readjusting in real time to the surrounding environment.

3. Digital hearing aids – a recent advancement — have drastically diminished the occurrence of pestering feedback, echoes, and background noises. These were par for the course as part of earlier technologies, and they made concentrating much harder.

4. In addition to the amplification of sound, modern hearing aids can also enhance and clarify sound.

5. When used in combination with special induction or hearing loops, hearing aid users can more clearly hear notices in public areas, meetings, airports, arenas, and other congested areas. This technology enhances sounds and minimizes all the background noise.

6. It used to be that hearing aids were only manufactured in beige and related colors to match people’s skin color, so that they were not easily recognizable. Today, users are welcoming their hearing aid technology, exhibiting a range of colors and patterns to show off their devices and stick out in a crowd.

7. Similarly, hearing aids are smaller in size than ever before. They used to be large, cumbersome gadgets that weighed several pounds and barely amplified sound. Today, they only weigh a few ounces and provide remarkably better sound quality.

8. Today, you can purchase water resistant and waterproof hearing aids to better fit in with your lifestyle. Water resistant hearing aids can tolerate low levels of humidity and moisture, while waterproof hearing aids can withstand higher levels of moisture during showering and even swimming.

9. Instead of having to frequently replace the batteries in hearing aids, many are now made with rechargeable technology to cut down on upkeep costs.

10. Hearing aids do much more than amplify sound – they can also contain special tinnitus therapy components that provide the user with relief when it comes to constant ringing in the ear.

Now that you learned some interesting facts about hearing aids and their accompanying technology, you can better understand what they have to offer the young and the old alike.

How Ibuprofen Can Lead To Hearing Loss

It’s true what they say about age leading to hearing loss, but you may feel like there’s not much you can do to help that aside from avoiding very loud situations. Now there is concrete evidence that ibuprofen, a common pain relief medication, has been connected to increased incidents of hearing loss in people as they age. This translates to the avoidance of certain medications in an effort to protect your hearing health. This is all prompted by a new study that emerged to back up this finding.

Causes

Even though researchers have done studies on ibuprofen and hearing loss occurring in men, no studies up till now had been done on women. Now we know. Do your part to improve hearing by refraining from taking certain medications. You should talk with your doctor to find out what’s best for your unique situation. You may wonder how pain relievers such as ibuprofen can bring on hearing loss. This, then, can reduce the flow of blood to the cochlear located in the inner ear. This makes it not work as it should normally. When you ingest acetaminophen, especially, you can harm the ear structures that are in place to protect your cochlea. Tinnitus, dizziness and vertigo can all be brought on through the ingestion of ibuprofen. Plus, some analgesics can damage your kidneys as well as your ears, characterized by ototoxicity.

Conclusive Findings

A study, conducted by the American Journal of Advanced Epidemiology, followed about 60,000 women over 14 years to conclusively determine that pain relievers like ibuprofen and acetaminophen can bring on hearing loss in women. It showed that a quarter of those women who ingested ibuprofen and acetaminophen more than twice in one week found a lessening of hearing ability.

More Research

The need for more research is important. That’s why the National Institutes of Health (NIH) is studying 150,000 women across the nation to determine all the many factors that can contribute to hearing loss. These factors impacting hearing loss can include hormones, diet and alcohol consumption, along with exposure to loud noises over a long period of time.

What to Do

Secure your doctor’s approval before taking ibuprofen, so you know how it can potentially incur hearing loss. Also, be sure to inspect all labels on cold and sinus medications found over the counter, because ibuprofen can be in them without you knowing. You may still ingest non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen muscle pain or headaches hit but if hearing loss is an issue with you, refrain from taking this medication to be safe. One alternative for you is to take naproxen instead, which is fine for your hearing.

How Hearing Loss Can Affect Your Holiday Gatherings

With so many parties and gatherings, you would think everyone would be having a great time at the holidays. Not so. Your hearing impaired friends may be having some difficulties. Hearing loss can deeply affect various aspects of a person’s overall happiness and health. The holiday season is a time when family and friends can come together to meet and revel in their happiness. Hearing loss can deeply affect various aspects of a person’s overall happiness and health. We’ll show you the effects of hearing loss on social happiness, how to manage hearing loss, and how to help people who suffer from hearing loss.

Hearing Loss Problems

The issues presented by hearing loss can be looked at as chiefly social in nature. If you cannot communicate with these people that you love, it can cause some significant effects on your overall sense of well-being. This is crucial in terms of hearing loss during the holidays because, more than anything else, the holidays are a time to gather with close family and friends. For example, people who suffer from hearing loss are much more likely to have issues with depression as well as anxiety. After all, being unable to take part in the holiday festivities is enough to get anyone feeling the holiday blues. This is only worsened by the fact that hearing loss may stop people from even going out and participating in any form of family activity in the first place. This social isolation will result in other problems in life as well, and can manifest in health problems such as brain damage and even dementia later in in life.

What Can We Do About Hearing Loss In The Holidays?

The first level of help that you can provide is by working through the basic barrier of isolation that these people with hearing loss put up. You can invite your hard of hearing family members to events and make them incredible welcome in your home. Specifically, bring them over and make sure that everyone completely understands their situation. Do not be afraid to break the ice and build the room’s conversations around them in order to build their confidence. Also, you can be sure to help people with hearing loss by making sure that you are speaking to them loudly and slowly depending on their overall preferences. Taking a person-first approach to their needs is a great idea. While the hearing loss can have an incredible impact on the way that people approach and celebrate the holidays, there are ways that you can do something about it.

Another way that you can combat hearing loss is to meet with a hearing specialist. These specialized medical professionals can work to the advantage of their patients by giving them the ability to examine possible hearing solutions available to them. After all the best way to help integrate family and friends with a more active community is being sure that they can actually hear conversations as they are happening. A hearing specialist will show you how to go about helping your hearing- surgical options and device solutions. Surgery can repair the physical structures of the ear that have been harmed throughout your life. In terms of hearing devices, there have been many advances in technology that have allowed hearing aid devices to give an amazing amount of hearing back to patients. With all of these means, hearing specialists are able to help people with their overall hearing health. They can also help them cope with the holidays.

How Hearing Aids are Programmed

Programming is an important component of your hearing device, no matter what your degree of hearing loss. How your hearing aid is programmed depends on your degree of hearing loss, comfort level and other personal considerations. You can’t simply purchase a set of hearing aids from a retailer without having them programmed to your specification. Just like glasses without the lenses, a hearing aid won’t do you any good without programming by a certified audiologist. This is crucial because your hearing aid needs to conform to your ears and your existing hearing capabilities.

What Factors can be Adjusted?

An audiologist is skilled in adjusting elements such as volume, frequency, intensity levels, compression ratios, max power output, noise reduction, microphone parameters and the like. Many factors are involved when programming a hearing aid. Depending on the model type you have, along with the software contained in it. Therefore, if one setting is too sensitive in regards to noise, it can be changed to accommodate the user’s comfort level. Many can be adjusted to filter out certain levels of background noise as well.

Processing Time

You may have to go back a couple of times to get your hearing aid adjusted. Did you know that the brain has to take time to adjust to the new sounds emitted by the device, which can only be determined over time when exposed to different environments? Most people come back to their doctor with suggestions on how the device could work better or complaints about what the device can’t do for them. Most hearing aids manufactured today are digital in nature, as opposed to older devices that could be adjusted with a simple screwdriver. Back then, you got what you got – there weren’t too many adjustments available. Fast forward to today and hundreds of elements can be fine tuned within digital hearing aids to accommodate the hearing needs of an individual. Programming takes place as a result of a complete hearing evaluation with the user on his or her subjective preferences. This trouble shooting approach is what’s so great about digital hearing aids.

Programming Hearing Aids

During the actual programming process, many doctors use a surround sound system to simulate real noise from the outside world and make adjustments based on real-time feedback. This surround sound system can simulate crowd noises to determine how they will go about noise reduction. This is a helpful feature because so many people with hearing aids say they work great when all is quiet but as soon as they are in a restaurant, or even at a train station, they have to work hard to compete with all that background noise. Through real ear measurements, visual mapping and environmental simulations, a hearing aid can be customized to the individual user. Real-ear probe microphones can detect how much sound is reaching the eardrum so the doctor can be the most accurate in his programming. Visible speech mapping (VSM) tells the doctor how various sounds of speech hit the eardrum. This is a great alternative to traditional measurements because today’s hearing aids can now help with noise reduction and feedback reduction algorithms. The process of programming a hearing aid requires the proper hardware, software and cables to connect to the hearing aid. Many people learn to program their own hearing aids but the equipment can get expensive and the level of accuracy goes down. However, a word of caution: have a qualified audiologist perform this important task for the ultimate in hearing health.

Brain Hearing Restores Optimal, Natural Hearing

In stark contrast to their bulky and expensive ancestors, modern hearing aids work much better thanks to technology and they are super sleek. They’re also pretty much invisible! The last 10 to 15 years have seen many advancements in this realm. Where hearing aids used to be bulky, expensive, and ineffective, today’s versions are much more discreet, affordable. They can also easily mimic subtleties of natural sound.

A fundamental change in the overall approach to research and design of hearing aids is now on the horizon. It’s called “brain hearing.” Unfortunately, hearing aid technology is being held by its reputation because many believe hearing aids are still ugly, massive contraptions of the past.

So what is brain hearing, exactly?

Because sound actually occurs in the brain, not in the ears, brain hearing is based on this premise. Traditional hearing aids are designed with the ears in mind. Thus, they amplify any and all sounds, pushing through lots of noise directly to the brain. The resulting sound quality is negative and just serves to tire out the brain.

The good news is that researchers have revealed they know that the processing of sound within the brain, and quality of the signal the brain receives, are just as important as the amplification of sound in the ear. By considering the entire hearing process, brain hearing research is leading to the emergence of some incredible hearing aids.

How do brain-focused hearing aids work?

Quite simply, brain hearing makes for better hearing aid performance. By modifying only the sounds that the inner ear cannot already hear well, the natural quality of sound is preserved, and the brain is not fatigued by amplification that is not necessary. By preserving a natural, clear signal, brain-focused hearing aids work with the brain’s four key functions that interpret the sound it gets:

1. Speech recognition – brain hearing preserves the natural characteristics of speech, making it easier to focus on conversations and switch between speakers.

2. Spatial recognition – brain hearing preserves the difference in sound between the two ears, allowing for the ability to accurately locate sounds.

3. Sound filtering – brain hearing preserves the ability to identify and separate relevant information from background noise.

4. Sound focusing – brain hearing preserves the ability to focus on relevant sounds and speech, even in noisy environments with abrupt changes in background noise.

How you can benefit from brain hearing

An appointment with a board-certified audiologist is your best bet. Next, your audiologist will precisely measure your hearing loss, using that information in the custom programming of your new state-of-the-art hearing aid.

Ask about how you can incorporate brain hearing technology into your hearing aid. While hearing aids need to be professionally fitted and programmed, the process is probably easier than you think. The best part is, you can start enjoying the sounds of life again, lacking the burdens of hearing loss courtesy of brain hearing.

Consumers love brain-focused hearing aids

Many companies are now producing brain-focused hearing aids, with very positive results. Oticon, for example, reports that while average hearing instrument user satisfaction is 79%, user satisfaction associated with one of its brain-focused hearing aids is 96%.

“Brain Hearing is a natural evolution of Oticon’s long-standing commitment to putting the needs of People First,” says Søren Nielsen, President of Oticon. “This comes back to our research from our Eriksholm research facility, where we have understood that treating hearing loss is much more than presenting sound through amplification. We have known for some years that the brain has a unique ability to process sound if it receives a robust signal that is full of detail.”

How Cell Phones Are Revolutionizing The Hearing Aid Industry

No longer is it sufficient to just use a hearing aid. You can now take advantage of the latest technology in conjunction with your hearing aid. Offering state of the art technology to accommodate the hearing impaired population, cell phones and smart phones now have special components that result in greater clarity of sound. If you never thought cell phones and hearing aids would go together, think again. In fact, both cell and smart phones are taking the hearing impaired community by storm, boosting the use of modern day hearing aids. For those with different degrees of hearing loss, sometimes a hearing aid just doesn’t do the trick. Cell phones and smart phones are now here to pick up the slack. Hearing aid devices have traditionally been the most popular way to help hearing impaired individuals hear more clearly in everyday life. Now to boost that capability, cell phones and smart phones can help with this even more so that people with hearing loss can tackle their day with increased confidence.

Smart Phones- Leading The Way

The earliest forms of the cell phones were not the technological strong holds that they are today. Nonetheless, they were still crucials on the long road of helping people with hearing loss use their phones with greater accessibility and confidence than ever before. For example, early cell phones integrated telecoils into their design so that people with hearing aids could use the phones without worrying about the interference or static that plagued early cell phone services.
Thanks in big part to static and noise cancelling technology that come equipped in the latest models people who use hearing aids can further take advantage of smart phone usage. The great thing about this is that there is virtually no feedback or static present when using a hearing aid together with a cell phone. This establishes the hearing aid capacity rating, or HAC, which acts as an objective rating for the cell phone’s ability to interact with a hearing aid; a rating that still exists in the modern era. Smart and cell phones can also alert users via a phone call or text with blinking LED lights to get the user’s immediate attention. Or, they can send vibrations when a message or phone call or text is received so the user can count on their device to notify them of any emergencies or conversations.

Cell Phone Technological Advancements

To make conversation clear, many modern cell phones come with a telecoil, which that is responsible for changing magnetic signals from the phone into sound signals that can be interpreted by the user. This occurs when the telecoil and the cell phone are used in conjunction. Most cell phones today must live up to a T3 or T4 standard, meaning they have met and surpassed the overall power and efficiency that they are required to have in order to function. You, thus, get a greater range of accessibility for your cell phone.
As you can see, phones and hearing aids allow for a clearer experience on a daily basis for hearing impaired individuals.

Electric Cochlear Implants: Functions and Benefits

The world is becoming clearer to many thanks to electric cochlear implants. There are many technologies available to people who suffer from a hearing impairment. While hearing aids, in all of their many editions, have been the most common solution to hearing loss, cochlear implants are becoming even more popular for individuals all over the globe. You must understand that cochlear implants are used for people who have a large amount of hearing loss, and can be a solution to both adults and children. With several technologies available to hearing impaired people, electric cochlear implants go beyond the traditional hearing aid to offer something superior to those with profound hearing loss. These devices attach to the person’s skull to make a bypass which allows sound wave to be interpreted by the auditory nerve. These differ from that of a simple hearing aid, which is worn in the ear.

How Do Cochlear Implants Function?

Cochlear implants, necessary for many people in which a hearing aid simply won’t provide the hearing help they need, allows users to experience crisp, clear sound waves for optimal enjoyment. Working through the use of four major components, all parts simulate hearing and work like a well oiled machine. The microphone is located on the outside of the ear. It detects sounds, then passes them on to the speech processor that is near the microphone, which can also be worn in other places on the body. This is where the interpretation and digitization of sound occurs in order for it to be picked up by the transmitter. The transmitter, which gives the signals to the receiver underneath the skin, passes all of the signals to the electrodes cluster located in the cochlea. This sits behind the ear and under the skin, where electrodes fire up special fibers on the auditory nerve.

Benefits of Cochlear Implants

Ideal for those who suffer from a high degree of hearing loss than cannot be addressed through a simple hearing aid, these devices allow the individual to clearly pick up on sounds such as speech and surround environmental sound. This helps the user feel safe in his or her environment as they go through their daily life. As such, electric cochlear implants are the best when it comes to the most integral hearing devices available to the hearing impaired community. Great for people kids and adults who live with a high degree of filter crowd noise.

What Makes A Cochlear Implant?

Most of the components of a cochlear implant are located on the outside of the ear, but some are placed under the skin and behind the ear. There are many significant parts to a cochlear implant. The microphone, speech processor, and a transmitter comprise the external parts of the device, while the receiver and an electrode cluster comprise the parts implanted under the skin.

Advancements in Digital Hearing Aids

Digital hearing aids make up a whopping 90 percent of all hearing aids on the market right now. That’s a pretty big feat, and there’s a reason for that. Technology has spurred this need on, allowing everything from filtration of background noise to connections to Bluetooth devices. Additionally, audiologists can now program each device according to the user’s specific degree of hearing loss. They have the ability to remove fuzzy and loud background noise, but this isn’t the only advancement around. Today’s hearing aids have come far since the 1800s, which is when the first ear trumpets arrived on the scene. While some are available with remote controls that allow the user to adjust various settings, others come with omni-directional microphones to detect sound from multiple directions.
Hearing aids were originally analog in nature but are now mostly digital.

Noise Filtration

Did you know that hearing aids can actually communicate with each other? They’re “smart.” Improvements in wireless technology have allowed for improved speech recognition and SNR, which stands for signal-to-noise ratio. A major issue for users of hearing aids is that it can be tough to properly hear with all the background noise going on. Older hearing aids amplified all sound, which was great for hearing words but this also presented an added challenge of filtering out the background noise that was also amplified. Many manufacturers, incorporating brand new technology through the use of digital magnetic wireless communication, use chips in the devices that control settings such as switch position and microphone modes.

DNR

Digital noise reduction technology contains technology that incorporates directional microphones. This is because there is a concentration on the physical characteristics of noise and speech instead of the separation of space, taking into account factors like speech modulation.

The First Digital Hearing Aids

The initial digital hearing aids were great for boosting processing speeds which improved the ability to hear as well as the range of amplification. This still rings true today. The first digital hearing aids featured DSP, ideal for digital noise reduction. DSPs, which stand for digital signal processing, were first available in 1996.

Single Sided Deafness

Things like CROS devices and bone conduction devices allow the good ear to receive signals from the bad ear to spike up amplification. People who had single-sided deafness prior to big advancements in digital technology were frustrated with background noise and were relegated to using their “good ear” to hear conversation.

Self-Learning

Did you know your digital hearing aid to learn on its own? It’s true. Self-learning hearing aids are integral to modern devices because they have self-learning or regulating tendencies. Digital hearing aids are great for adjusting settings like volume automatically after a period of time according to how the user prefers it. Control is put into the hands of the person wearing it, which is yet another advancement.

Better Connections

People wearing digital hearing aids benefit from digital noise reduction and better frequency transposition due to improvements in digital hearing aids. They can also enjoy increased range. Hooking up to Bluetooth and other wireless technological services is par for the course now.

The Outlook

Digital hearing aids represent the future of these types of devices, bringing increased versatility and comfort to their many users around the globe. Now, hearing impaired individuals have innovative wireless technology and microelectronics at their fingertips at all times to improve their daily lives.

10 Ways Good Hearing can Help Keep Seniors Young

Just as physical fitness is ideal for you waistline and heart, healthy actions when it comes to your ears are integral to many factors in your life. Here we discuss how good hearing can help you maintain your youth. With top-quality hearing, you can hold onto your youth for longer. With a better social life and self-esteem, maintaining your hearing health is critical. By maintaining your hearing, you’ll experience lots of great side effects that make you feel young. By picking up on sounds quickly when they occur, you can ward off potentially dangerous situations fast.

  1. Up the flow of blood to your ears. Every time you engage in exercise, you send excellent oxygen-rich blood flow to the ears, which protects the ear canal and makes it less likely you’ll experience additional hearing loss.

  1. When your hearing is crisp, you can better react to fire alarms, sirens and anything else that threatens your safety.

  2. Better job performance and job prospects. When you lack good hearing, you naturally can’t hear important instructions or safety precautions. You can’t even participate productively in coworker discussions or meetings, affecting both your job performance or edge you out of your profession.

  1. Keep dementia from setting in. Hearing loss and dementia are related, says the National Institute on Aging. As we age, our brains shrink, especially in those who have hearing loss. But this shrinkage also brings an increased risk of dementia.

  1. More productive interactions with others. Hearing loss can alienate you from getting the information you need to lead a successful life. With a hearing impairment, it’s difficult to communicate with anyone from your boss to your friends. Instead, having better hearing means you feel more confident that you can easily talk with others, allowing you to stay engaged in the moment.

  1. Better social and sex life. Hearing impaired seniors who don hearing aids have been known to experience an improved social life and sex life. In addition, they have better overall mental health and a sense of independence.

  2. Increased sense of confidence. Those with difficulties in hearing can have a lack of self confidence or self-esteem because they can’t interact easily with others in social situations like parties. The result? They may avoid going to parties, meetings and get-togethers because of this fear.

  3. Hear teachers better while in school. You won’t learn as well if you constantly have to sit up front and ask the teacher to repeat herself. Keeping up a good level of hearing health means you can understand the teacher’s instructions more clearly and thus have an overall easier classroom experience.

  4. Fewer hospitalizations. Hearing loss can boost your risk of going to the hospital due to falls and other events, can actually lead to inactivity, which in turn leads to depression.

  1. Less chance of falls. Individuals who can’t hear well don’t have as much of a stable awareness of their surroundings, and can trip and fall easier. You don’t have as high a chance of falling when your hearing is as good as it should be. People with a 25-decibel hearing loss are three times more likely to fall than others with no hearing impairments, according to Johns Hopkins Medicine.
