A site dedicated to the review and analysis of potential sasquatch vocalizations, Sasquatch Bioacoustic combines techniques from the domains of intelligence collection, audio analysis and bioacoustic studies to examine the evidence of sasquatch through their vocalizations. ~Monongahela

Using Your Recorder as a Bionic Ear

During my last outing I took a different approach and positioned myself high on a ridge. I sat there quietly in my truck for about three hours, listening to the night sounds around me. But instead of just letting my recorder roll and listening with my ears the way I have in the past, I took advantage of the quiet (I was out solo) and plugged my headphones into my recorder.

The difference was like night and day. I had my mics positioned up on the roof of my truck, pointing in two opposite directions. I sat comfortably in my driver's seat and listened through the head phones. The mics and recorder functioned just like a bionic ear and pulled in all kinds of faint sounds that I wouldn't have heard using my own ears.

At one point I heard a weird moaning sound, kind of ghostly, somewhere out in the forest. It might have been an owl, but at the time it was certainly a weird sound to hear. And soft stick cracks emerged from all around me as twigs dropped from trees and deer/rodents scurried about.

So if you haven't tried this approach, give it a shot next time you go out recording. When you're sitting quietly, it makes a world of difference (but the noise would probably be overwhelming if you tried this while walking). I used ear buds, and they worked pretty well, but over the ear headphones should do better, if you have them.

A Faint Howl

This weekend turned up very little good audio. Increased human activity in my Monongahela National Forest research area seems to have put off the vocalizers that I've heard consistently the last few months, or possibly forced them to move out of the immediate area.

I did however find two faint vocalizations while reviewing my audio recordings. The first is a distant, faint howl captured at 11:13PM on June 11, 2010. It's interesting though because its fundamental frequency appears to be about 490Hz, much lower than the typical low end for coyotes. The form is also very flat, similar to the moaning howls recorded from Washington state, and somewhat like the Ohio, Mississippi or Florida howls:

Nearing Launch

The web collection of potential sasquatch audio assembled http://sites.google.com/site/mongahela is making steady progress toward its launch date. So far the most significant classes of vocals have been established, and largely populated with audio studies culled from various contributing researchers. Explanatory prose is under development and a domain name may soon be registered.
