Lang Elliott has just posted the following announcement on the nature
recordists' email forum. I don't usually recommend products. Indeed I have
not seen this particular product and fortunately I do not need it yet. But I
do know lots of CarolinaBirders who complain about not being able to hear
birdsong. This product might help. It is not cheap, but check it out if you
need it. Lang is a very reputable guy, and I trust his claims.
If anybody in this group has high frequency hearing loss and cannot hear the
high pitched birds and insects, then you must check out the new SongFinder,
a Digital Bird Song Hearing Device:
As many of you know, I myself have severe high frequency deafness and I have
been active for years in developing a solution to my own problem. The
SongFinder is the invention of myself and my engineer partner Herb Susmann.
It is designed for birders who are high frequency deaf but who can still
hold a conversation without using hearing aids. It takes high bird and
insect sounds in the 3-10 kHz range (and higher for the SongFinder Plus) and
then pitch-lowers these sounds into a range where one's hearing is normal.
There are three "divide-by" algorithms employed in the Basic unit: 1/2, 1/3,
The device is absolutely amazing in the field. Utilizing a binaural headset
fitted with full range condensor mikes, the user is not only able to hear
the high bird sounds but is also able to determine the location of singers
in the surroundings. The pitch-lowered sounds are clean and natural, and
seem to come from "out there" in 3D space.
