Why do fly's buzz when they fly?

Answer 1

Flies are among the fastest of all flying insects. The buzzing of a fly is the sound of its wings beating. A house fly's wings beat about 200 times a second, and some midges move their wings 1,000 times a second. House flies fly at an average speed of 4 and 1/2 miles (7.2 kilometers) per hour. They can fly even faster for short distances to escape their enemies, which include people and many birds.

Answer 3

The actual sound is differential pressure waves caused by the movement of the wings through the air … the physical properties of the wings also contribute but its mostly air pressure. Think of the noise a fan or helicopter blade makes cutting through the air, that’s a similar(ish) principal. If a fly flies close enough you can actually feel the disturbance in the air made by its beating wings. Your ears respond to pressure changes in the air …. hence the buzz

Answer 4

it's the frequency their wings are flapping. because they're flapping so fast, instead of hearing a normal wing-flapping sound like you do with a bird, it just sounds like a buzz instead. they flap their wings almost 200 times a second, which is why it sounds more like a buzz than anything else.

i guess they have to flap their wings so fast because they're so small to get some lift to actually fly.
