I received my first set of hearing aids today (phonak audeo p70-r) and have been trying to get used to them. I noticed a strange artifact in my left device; I will occasionally get a high-frequency (close to 3500 hertz, hard to be accurate) low decibel pulse that accompanies other sounds. I do not notice it during normal conversation or when there is a lot of other sound - usually only when the environment is quiet and a sound stands out (like, as I type this message in a quiet room and hear the clacking of my keys). Through experimentation, I found that if I touch the wire I do not hear the sound. If I reposition/reseat the device in my canal, the sound seems to disappear for while, but eventually comes back.
Any ideas what it is, and how to correct it? (I will obviously follow up with my audiologist - just seeing if anyone had any thoughts to share here)
