Losing audio in front of a certain house may be related to devices I’ve noticed my own neighbors beginning to use, which are those high pitched audio emitters that ward off voles etc. We don’t have that issue in our neighborhood and especially in front yards so I suspect it’s to keep dogs from pausing in their yard.

In any case it’s a periodic high pitched burst. I wonder if that was what caused your issue with the phonaks. Seems like it would be a rather common issue in suburbs that should be considered in hearing aid design.
