“It does sound like entrainment you are experiencing. The hearing aids were using an obsolete method of trying not to whistle (feedback) and in doing so they sometimes confuse themselves when they hear certain noises, and ‘panic’ adjusting themselves in such a way they end up making stupid noises as you describe. The good news is that modern hearing aids shouldn’t suffer from this problem. Those Audibel aids sound like they need some adjustment to get the best sound.”
I think we have a problem with semantics here. There are two different effects that I’ve noticed with the Phonak Naida that I wear in my left ear (I have a CI in the right ear).
The first effect is a “rushing” type sound that trails each instance of sound input. When the sound input stops, the rushing continues for a few seconds and then stops. It’s extremely irritating.
The second effect, which I described in my earlier post in this thread, is a “warbling” effect. It is not a sound in itself, but a distortion of sustained sound input (mostly music). It makes me think of an underwater “bubbling” effect. As Lola Hagerty said earlier in this thread, it makes listening to music almost impossible.
