Guidelines for Musicians with Hearing Loss to Bring to Their Audiologists

The music programs in the major manufacturers’ hearing aids are often “poorly thought out,” with “very little effort and research” put into them, declares Dr. Marshall Chasin, a Toronto-based researcher and audiologist who specializes in musicians with hearing loss.

In this first article of our new series on how to customize your hearing aids for playing and performing music, GRAND PIANO PASSION™ is pleased to offer this collaboration with Dr. Chasin: his comprehensive checklist to bring to your audiologist to create a music program suited to you and your hearing aids.

Music programs generally do not take into account musicians’ needs to hear unadulterated sound across the full frequency spectrum because hearing aids are optimized for listening to speech. “In speech, you can miss certain things, you can fill in the blanks,” explains Dr. Chasin. “But with music, we have to actually hear everything. So, we need hearing aids that replicate music precisely.”

Interestingly, Dr. Chasin thinks, “It’s best that the audiologist you see does not play any musical instruments. The moment you start playing a musical instrument you have these preconceived ideas and notions. It’s better if you go to an audiologist who just understands the technical differences between music and speech.”

Dr. Chasin’s Checklist for Your Audiologist to Create a True Music Program on Your Hearing Aids

Start with Post-16-Bit Architecture

What to tell your audiologist: First, be sure to select hearing aids that have 20-bit or 24-bit architecture to allow for a higher input level. Then start with the optimal “speech-in-quiet” program for the patient and make adjustments from there to create a custom music program.

Here’s why: In some hearing aids, all sounds can’t necessarily get into the hearing aid for processing because the old industry standard 16-bit systems have a maximum input level of 96 decibels. Music can be louder than speech with more dynamic peaks, so louder elements would be clipped or distorted. Many newer hearing aids do not have this problem, but it’s important to make sure you’re starting with an appropriate model.

Dial Down Compression

What to tell your audiologist: A low compression ratio of 1.7 to 1 (or a maximum of 2 to 1) is best for music.

Here’s why: The compression ratio represents the change in loudness that comes into the hearing aid versus the change in loudness that goes out of the hearing aid and into your ear. Too much compression essentially overprocesses the sound, causing music to sound dull and lacking in dynamics.

Turn Off Noise Reduction

What to tell your audiologist: Disable the noise reduction system for the music program.

Here’s why: The noise reduction system is designed to reduce the sound of the microphone inside your own hearing aid, but this feature sometimes has detrimental effects when used for music.

Turn Off Feedback Management Circuit

What to tell your audiologist: Disable the feedback management circuit when setting up the music program.

Here’s why: The feedback management circuit is designed to prevent you from hearing the squeal of your own hearing aid. But sometimes it can’t distinguish between the whistling of your hearing aid and a harmonic or a musical instrument.

Turn Off Frequency Shifting

What to tell your audiologist: Disable any frequency shifting or frequency transposition for the music program.

Here’s why: Frequency transposition customizes sounds to your particular audiogram by moving some tones to a lower frequency. It can help a lot when listening to speech—but for music, it means your hearing aids can actually change the notes and octaves on you if this feature is turned on!

Should your audiologist have additional questions, Dr. Chasin refers them to this article for practitioners.

We’d like to hear from you. How was your experience in working with your audiologist to implement this checklist?

  1. I am a piano teacher with hearing loss, and experienced a sudden onset of more serious loss just 2 years ago. I made a change to Oticon hearing aids last summer, but am still having trouble with what I am hearing. I took your article to my audiologist and he confirmed that he is configuring as you stated in your article. I have a special setting for music, but I still have some buzzing and feedback when I play. I also have trouble hearing inner voices of chords and sometimes half-steps are not clear. Is this all my new normal? It has really been tough to teach upper level repertoire at times, because of the difficulty in hearing the quick changes and subtleties of the music. Any advice you can give, for myself or for my audiologist, would be greatly appreciated.

    • Hi Carol, thanks for writing, and I’m glad to hear that your audiologist created a setting based on Dr. Chasin’s advice. I’m not an audiologist, but if I were in your shoes, I would go back to my audiologist for additional programming if I still heard buzzing and feedback while playing. If your audiologist feels that he has done all he can, Dr. Chasin is available to fellow audiologists who have additional questions after implementing his recommendations. Hope this helps, and great to hear that you teach!

  2. Hi Nancy, Thank you so much for your reply. I made a follow-up appointment with my audiologist. I have another question for you. Is there something he and I need to focus on so I can hear ½ steps more clearly? I have the most trouble in the lower middle register of the piano.

    • Hi Carol, glad to hear that you made a follow-up appointment with your audiologist. I don’t know the answer to your question, so I forwarded it to Dr. Chasin. More soon, I hope. Best, Nancy

      • Carol, I’m passing along this message from Dr. Chasin: “I would suggest that she ask her audiologist specifically about this- that’s something that is easily adjusted. Her hearing aid just needs a larger vent.” Good luck with your appointment with your audiologist. Best, Nancy
