I want an inexpensive way to connect a hydrophone to a
 PC such as to the RCA mic jack of a laptop or a PCMCIA
 Btw, by connecting a hydrophone, which typically has an impedance
 corresponding to 3 nanoFarad to a microphone preamplifier, which typically
 has an input impedance of 10 kiloOhm, you get a low frequency cutoff
 frequency at 1/(2 * PI * 3 nF * 10 kOhm) = 5 kHz. So you end up with a
 frequencyresponse, which is flat from 5 kHz to 20 kHz, which is not quite
 what you desired.
