A hydrophone is a microphone designed to be used underwater for recording or listening to underwater sound.

Used in World War I, hydrophones were employed by convoy escorts to detect U-boats, greatly lessening the effectiveness of the submarine. From late in World War I until the introduction of active sonar, hydrophones were the sole method for submarines to detect targets while submerged, and remain useful today (source: wikipedia).

Come and build your very own hydrophone in this two-day workshop! Clay Chaplin will lead you through the construction of your hydrophone using a kit we’ll provide, then test it out in the neighborhood.

Sorry, sold out! Email machine@machineproject.com to be added to the waiting list for future sessions.

Class 1
Sunday, August 16, 2pm–4pm
Part I
with Clay Chaplin

We’ll have hydrophone kits for your enjoyment. Minimal soldering experience required and plus we’ll help you. While constructing our hydrophones we’ll talk about field recording and more specifically about the properties of sound underwater and how hydrophones work. Once you’ve built your hydrophone take it home for a week and make a bunch of recordings.

Class 2
Sunday, August 23, 2pm–6pm
Part II
with Clay Chaplin

Bring your hydrophone, your trusty field recorder (we’ll be able to supply a few to borrow if you don’t have one), and any recordings you have made. Right off the bat we’ll all head to the lake to record what lurks beneath the surface. Then we’ll trek back to Machine and have a listening party. The real fun of making field recordings with a group is listening to everyone’s recordings.
