B) Bat Think about it... Bats use echolocation, which is basically a super high frequency sound wave, barely audible to humans, to find their food. 67,000 Hz is super high frequency, relative to human hearing of course. Bats would NEED to detect high frequency sounds if they wanted to detect their very own "echos".
Which of the following animals could detect sound at a frequency of 67,000 Hz? A. Dog B. Bat C. Elephant D. Tree frog
