Question:
My question is what animal can hear at 175,000 hertz
(which is a sound wave? My science book has a chart of animals that can
hear hertz. Would you please help me find which one or ones can hear at
175,000 hertz.
Replies:
The frequency that you've asked about is in the range used for
echo-location. Many cetaceans (whales and dolphins) and pinnipeds (seals,
walruses, and other things with flippers) can make and sense sounds in this
range. For these species, they detect the sounds with cavities in their
skulls as well as ears.
Bats also use echolocation, but most of the frequencies they use are a bit
lower than 175,000. You can find lots of neat information on bats at:
