Under the Delaware

Image

Independence Day in the States just rolled around and what better place to spend July 4th than the Delaware River?  If it’s good enough for George Washington it’s good enough for me.  I am still trying to get to know my new hydrophones and the bottom of the Delaware was where they ended up for a few hours. There are little rocks on the river bottom, so the trick was not to get the sound of the mics scraping them and actually recording the current rolling by.

If you listen closely you can hear different forms of air traffic filtered through the water.  I also wanted to test the mics ability to be almost crushed, so I picked up a few rocks from the surface of the river and threw them towards the capsules and ended with an interesting effect.  Luckily I only came close to the capsules so they can be used again.

Recording geek note:  Tracked with 2 Dolphin Ear Pro hydrophones to a Sound Devices 744T recorder at 24/96.

  1. Great to hear more from the hydrophones. Any commentary on how you suspended them in the water, i.e., were they resting on the bottom or floating freely? Great field recording, keep up the great work, and yes, post more hydrophone experiments..! 🙂

  2. Thanks for the comments. I tried both methods . . . on the surface on the river and suspended mid stream. I found the recording on the surface a bit more interesting, but more experiments need to occur. I’m still not totally satisfied with my results yet.

  3. Excellent stuff – interesting.

    How far apart were the two hydrophones? For me the first aeroplane localizes well, tracking from left to right, which was totally unexpected. The second one stays mostly in the left channel.
