DE500 Sound Samples:

 HUMPBACK WHALE SONG

Humpback whales are well known for their long complex songs that can last for 30 minutes or longer. Only male humpbacks sing - leading researchers to conclude that they sing to attract females. Interestingly, all of the males in an area sing the same song - repeated over and over - changing but little over the course of the year.   Whales in other areas sing songs with different melodies.  

Lower audio frequencies are attenuated less in seawater than higher frequencies - thus giving them greater range.  Their vocalizations are easily monitored by the DE500 wireless hydrophone.

Locating a DE500 in the breeding areas produces spectacular listening even if you are 12,000 miles away!
