Answer 1

A bee produces a buzzing sound through the quick movement of its wings when it flies. A bumble bee produces more sound by the movement of both its wings and the thorax. This does not happen when a crow gently flaps its wings when it flies.

Answer 2

when a bee fly we hear the sound by its wings because the wings of a bee flap very rapidly and as it flies near us we can hear the sound produced by it. Moreover by rapid movement of wings, the pitch of sound is more whereas in case of crow, its wings size are big so they do not have to flap them rapidly to fly. So we can't hear the sound of their wings produced by crow.
