Humpback Whales in Hawaii
The following three recordings use the H2a hydrophone
The following recordings were made with little to no effort in the recording setup, using an inexpensive Zoom H2 recorder.
This humpback whale recording was captured while demonstrating a hydrophone to Trilogy Excursions of HI while on a very pleasurable scheduled tour to Lana'i in February of 2009. The recorder was being used as a preamp and patched into the stereo system for customers to hear.

Reef Sounds with Humpback Whales
This recording of reef sounds with humpback whales was made from a kayak while just offshore of Kihei, HI. The whales were approximately two miles offshore.

Pacific Tree Frogs
This recording of frogs was made in the pond behind our shop with my five-year-old son. We just put some fresh rechargeable batteries in the recorder and let it record overnight. Play this 30-second clip over again 750 times and you'll pretty much have experienced the whole recording (I think; I didn't listen to the whole thing.) Our UPA-1 preamp (now obsolete) was included in the recording setup.

Human Body Sounds: hydrophone as stethoscope
Recording uses the H2a-XLR hydrophone
After several inquiries, we decided to make a short demonstration recording where the hydrophone is used as an electronic stethoscope. Includes heart (subwoofer or good headphones required), breathing, and abdominal sounds.
