DE500 Sound Samples:

Gray whale vocalization

Gray whales aren't well known for their vocalizations which sound more like 'grunts' than songs. Still they are easy to locate and their voices carry quite a distance owing to their low pitch.

When examined, the gray whale vocalization looks like a short series of tone bursts.

The frequency range of these vocalizations is typically under 1500 Hz.  We would love to see a series of DE500 spread out in the breeding lagoons of Baja California Mexico each December - April.

Here are some more samples - all using transmission band- widths of 3500 Hz or less!
