Tests with induction coil pick-up

I got my induction coil pick-up today in the post. I'm totally new to the idea of this gadget, but basically as far as I understand it picks up the electronic whirrings and signals given off by most electronic devices when placed near or against them.

Here are the first couple of recordings I made by moving it around my MacBook...

  Hard Drive Sounds by miles out in the field

  Laptop Sounds by miles out in the field

DolphinEar Pro Hydrophone

Last month I borrowed a DolphinEar Pro hydrophone from the Wildlife Recording Society. It's a terrific microphone, I got the chance to test out some ideas I've had for awhile.

My final year project will certainly draw upon this first recording I made...

  Mylor Boat Yard by miles out in the field 

This recording was taken inside a small cave, the acoustics of such spaces near the sea is fascinating.
