WIRELESS DolphinEAR:
From $695 for the 'Application' System
DE500 Sound Samples: Each dolphin has its own unique 'signature whistle' that identifies it from others. Listening to these whistles lets you identify individual animals. For the most part, these whistles are primarily low frequency sounds (below 3500 Hz).
The chart above shows the amplitude of dolphin signature whistles.
In this example, there is a rapid drop off of sound energy below 3500 Hz. Even when whistle components extend above this range, they contain significant low frequency components that are clearly identifiable with the DE500 wireless hydrophone making wide ranging dolphin population studies possible.
More samples - all using transmission band- widths of 3500 Hz or less! |
