We get many requests from the general public on how to listen to cetacean sounds. This requires a hydrophone, a device made of one or more piezoelectric elements that can cost up to 300 pounds for a professional quality device. As a much cheaper solution for the hobbyist, we have designed a simple-to-build device using very cheap components available from many sources. Headphones / tape recorders / etc. can be connected to the output of the preamplifier circuit in order to hear / record the cetacean whistles.
Construction details are available in Acrobat format (this link takes you to a site from where a freeware viewer can be downloaded).
We are unable to provide technical support on these items, but full construction details are included in the documentation.
