I;d like to add to Ambrose' list:
Firstly, at the bottom end of the price range there are the Sound
Professionals SP-TFB-2
http://www.soundprofessionals.com/cgi-bin/gold/item/SP-TFB-2
These are about $US70, and the cute thing about them is that they fit in
your ears, but they don't block the ear canal. They make good recordings
but they are not particularly low noise, and they don't work well for loud=
sounds either.
At the high end of the price range is the Bruel and Kjaer 4101
http://www.bksv.com/pdf/Bp1992.pdf
These work extremely well. They have a self noise of 23 dBA, and maximum
signal level of about 115 dB SPL. What they are, are DPA 4060 capsules (DP=
A
is a spinoff from Bruel and Kjaer) mounted on a stethoscope-like affair,
which places the capsules at the entrance to your ear canals. Very
convenient, but uncomfortable to wear for longer than about 30 minutes.
These are somewhere between $US3000 and $US4000. That's a lot to pay for
two capsules that sell for about $400 a piece individually!
I can post sample recordings made with either binaural microphone in
conjunction with a Microtrack 2496.
I also have plans to make available a binaural microphone product that will=
be in the price range of a single DPA capsule, but offer equivalent
performance to the Bruel and Kjaer set. This setup has an appearance
similar to a behind-the-ear hearing aid.
