Entrainment Issues

I first learned about entrainment last month from my audiologist. I mentioned to him that at work, when the security gates sound, the sound continues in my ear for a second or two after the actual sound is gone. He explained that the term for that is entrainment, when the sound is on the same frequency as feedback and the hearing aid kind of gets stuck in a loop. Unfortunately it doesn't seem to have stopped just at the security gates.

It took me awhile to figure out, but music in the car seems to be doing the same thing. I noticed with a few songs (of course, I can't remember any titles off the top of my head) that I'd start to feel kind of irritated during the song as though it were louder than it needed to be, no matter how the volume was set. Then after the song ended I'd hear a bit of ringing in my ears. I don't know why I didn't put two and two together, that it's entrainment and my hearing aid is probably giving me feedback throughout the entire song, just drowned out by the music. If it's really something that can't be fixed this is going to be annoying! I have to keep the volume of music very low in the car to avoid the problem, which means I may as well just not listen to anything. And once the hearing aid starts giving me feedback it doesn't seem to want to stop.

I'm definitely going to mention this at my next appointment with the audiologist. I hope it can be fixed!

  1. Wow, that's so weird! I've never heard of it before, but it certainly makes sense. I don't recall it ever happening to me, but it's entirely possible I just didn't know what it was or notice it was happening at all. I'd be really interested to know how your audiologist fixes a problem like that-it seems really complicated.

  2. Yes, before I got these new aids I never experienced this problem. I'm curious to see if there's anything he can do since it didn't sound like it at my previous appointment!

  3. The same thing happens to me! It only happens when I am in my car palying music--and it is only certain types of music that cause it to happen. I will definitely get a second opinion. My audiologist told me that it probably has something to do with the tubing on my hearing aid. But, my hearing aid is working fine and when I replaced my tubing, it still happened.
    It is nice to know that I am not the only one who is experiencing the same thing.
    Let me know if you find out anything.
