I have hearing loss in both ears, no tinnitus. My ENT doctor has been monitoring it for some time and this year my hearing test indicated it was time for a hearing aid. I knew my hearing had deteriorated significantly, as I was unable to hear the true timbre of a violin, cymbals had all but disappeared from some of my favorite jazz trios, and so forth. The hearing test identifies the degree of loss by frequency. I tried a pair of high quality Widex hearing aids and the difference was nothing short of astounding. Most of the sound I had been missing is back.
The audiologist showed me a graph of my hearing loss, which begins at about 2k Hz, building to 20 dB of loss over 6k Hz (a lot), pretty similar in both ears. The hearing aid boosts the signal between 2-6k Hz, but doesn’t do much above that. There is software you can download to your Android or iPhone that has different baked in settings for normal use, music and crowds. Plus you can listen to music and create your own settings for different types of music if you choose. There are also manual volume and balance controls.
Clearly the hearing aid is an audio device that has some effect on the signal you are processing, just as your audio equipment does. But if you find you are significantly missing something in your listening by all means try a pair quality hearing aids after consulting with a good ENT or audiologist. Where I live state law gives you a trial period during which you can return the devices if you don’t like them.
I am enjoying my music so much more now that I can hear instruments and a presentation that sound more lifelike and natural.
