* Note: frequency response
is given for entire system including earphones. This limits the
frequency response to normal human ranges. When using the spectrogram software
(included) for recording sounds directly from the DolphinEAR, the useful
low frequency range extends down to a few Hz; the upper frequency range
extends to more than 22 KHz. DolphinEAR is designed for casual recreational
use, but is rugged enough for demanding commercial and industrial applications
, or research projects.
