The Link Between Hearing Loss and Cognitive Decline
Recently, the Hearing Center at Jacksonville Hearing and Balance Institute partnered with Phonak (a major hearing aid company) to give a presentation to the community regarding the connection between hearing loss and cognitive decline in older adults. Unfortunately, it filled up too quickly for us to accommodate everyone who wanted to attend. Just in case you missed it, here are some of the highlights from the presentation:
The study in question was conducted by Frank Lin, Ph.D. and his colleagues at Johns Hopkins University using information gathered from older adults over a period of decades. The researchers found that those individuals with untreated hearing loss (whether it was mild, moderate, severe, or profound) were significantly more likely to experience cognitive impairments than their normal hearing peers.
But just how are hearing loss and cognitive impairment connected? As Dr. Lin reports, “Your inner ear has to take in a complex sound and convert it into a signal that goes into the brain. When we say that people have hearing loss, it means the inner ear is no longer as good at encoding those signals with accuracy and fidelity. So the brain gets a very garbled message — you can hear what’s being said but you can’t quite make it out. It takes a little more effort to hear what that person said. As a result, the brain has to re-dedicate sources to help with hearing and sound processing. That comes at the loss of something else.” Dr. Lin also notes that, “As we develop hearing loss, we withdraw socially. You’re less likely to go out and you may be less likely to be engaged in conversation.”
While more research needs to be completed regarding the link between hearing loss, social isolation, and cognitive decline, these early results certainly emphasize the importance of hearing heath on one’s overall health. Unfortunately, up to two-thirds of adults with hearing loss remain untreated. Here at JHBI, we hope that by increasing awareness about this topic, we can identify hearing impairments and possible intervention strategies earlier rather than later.

Boosting Your Hearing Aid Performance with Wireless Technology
Even with the best hearing aids, it can still be difficult to enjoy your favorite song or your favorite TV show, or hear a speaker clearly in a business meeting or at a restaurant. It may even still be difficult to hear someone talking to you on the phone. Over the past 10+ years, hearing aid manufacturers have developed wireless accessories to accompany hearing aids. These devices can be used in even the most complex listening environments. Today, some hearing aids will even connect directly to iPhones. Below is a list of outlined accessories and their uses as well as more information regarding direct connectivity options.
Several hearing aid manufacturers now offer direct-to-iPhone hearing aid options. Starkey, Oticon, Resound, and Widex hearing aids can be connected via bluetooth straight to your cell phone and most apple devices! Each manufacturer has their own free, downloadable, and user-friendly app which can control your hearing aids, including volume control, program changes, and some even allow you to control the directionality of your microphones in different listening situations. Phone calls are streamed directly to your hearing aids; your music, a video, a movie, anything streaming on your phone…that’s right! It goes straight to your hearing aids! They have now become wireless headphones!
Cell Phone Accessories:
With the technology of bluetooth, connecting your world to your hearing aids has become easier than ever. Several manufacturers offer wireless accessories that either clip to your lapel or hang around your neck. These intermediary devices allow your cell phone to talk directly to your hearing aids. As long as you are wearing your clip-on or your neck loop, your phone calls can stream directly to your hearing aids, as well as any other audio streaming from your cell phone. All it takes is a simple pairing procedure which your audiologist can help with!
With a TV Link, you will have the audio from the TV streaming directly into your hearing aids. All you have to do is hook up the accessory to your TV. Enjoy the comfort of listening to your favorite show at the volume you prefer while your loved ones can still enjoy the show at their preferred volume. Most TV Links require an intermediary device, however, which connects to the hearing aids and the TV Link then connects to the intermediary device.
Many manufacturers make accessory options in the form of a remote microphone. Remote microphones significantly improve the signal-to-noise ratio in noisy environments. Although most hearing aids at all technology levels reduce background noise levels in noisy environments to some degree, a remote microphone brings the speaker’s voice directly to the hearing aid users’ ears. The speaker wears the remote microphone and the listener wears an intermediary device which streams the signal to the listener’s hearing aids. This makes for exceptional speech understanding in noise and better understanding over longer distances. Some remote microphones can transmit to the users’ hearing aids from up to 80 feet away!
If you would like to learn more about these devices for your hearing aids and learn what your options are, schedule a hearing aid consult with an audiologist today! They should be able to answer any questions you might have! Just call: 904-399-0350
