Question 1 of 10
Constructing TextsDraft: The Quietest Wings
1(1) Most birds make a soft whooshing sound when they fly. (2) Owls, however, can fly so quietly that their prey often never hears them coming. (3) Scientists have spent years trying to understand how they do it.
2(4) The secret lies partly in the owl's feathers. (5) The front edge of an owl's main wing feathers has a row of tiny, stiff points, like the teeth of a comb. (6) These points break up the air flowing over the wing, which reduces noise. (7) The feathers also have a soft fringe along the back edge, and they have a velvety surface.
3(8) An owl's body shape helps, too. (9) Owls have large wings compared with their body weight. (10) They can fly slowly without flapping hard.
4(11) Engineers have been inspired by owls. (12) Some companies have designed fan blades with comb-like edges that make less noise than ordinary blades. (13) Others are testing similar designs for wind turbines and aircraft.
