Friends,

I'm sure I don't have any hearing loss, but I have noticed that kinglets
and ground squirrels have become much quieter in the past few years. Do
any of you have experience with a gizmo that transposes high frequency
sound down to a lower frequency? I've heard there is such a thing for
people with a larger endowment of annulla or a noisier past.
