Question

a dog can hear high frequency sounds which a human ear cannot .is it true and why ​

Answer 1

Answer:

Dogs, on the other hand, can hear sounds as high as 47,000 to 65,000 Hz. These are sounds far too high-pitched for us. ... That means dogs can hear sounds that are not loud enough for our ears. For sounds above 12,000 Hz, dogs' ears have sensitivity so much higher than humans that a comparison would be pointless.

Hope it helps. Jai Shri Krishna
