1. VocalZoom has a microphone which uses
optics instead of sound vibrations through the air. It is essentially
unaffected by high ambient noise. An infrared beam detects skin
vibrations of a person speaking. This is most apparent around the
throat, but much of the face provides sufficient feedback for the
sensor. Electronic Design Fe2017
2. At present I am listening to an audio
book of Musicophilia by the late Oliver Sachs. He was a neurologist
and it is case histories of people struggling to deal with auditory
neurological conditions, from the man who was struck by lightning
and suddenly was inspired to become a pianist, to people with amusia,
to whom a symphony sounds like clattering of pots and pans, to a
man whose memory spans only seven secondsfor everything but
musicto people with nonstop musical hallucinations. It's all
interesting, but neurology has little to help these people. It was
a free download through my public library, from overdrive.com.
