Question

When a bird flaps its wings,do you hear any sound

Answer 1

yaa when birds are happy then they flap their wings yaa if it is close to us then we can hear the sound

Answer 2

The sound also changes as birds flap faster, such that those fleeing danger produce wing sounds with a higher tempo. In fact, the birds' wings produce alternating high and low notes in flight. The researchers' experiments showed that the eighth primary wing feather is responsible for the high notes.

Due to high frequency , the sound reaches out of the hearing capacity of a human ( 20 hz to 20000hz).

That is why we don't hear any sound.

Hope will help.....
