Wind

Can wind carry sound further

Can wind carry sound further

Yes! Wind carries the sound wave, so, relative to the ground, it moves faster and further. In addition, because windspeed increases with height above the friction layer (about 3,000 feet), the then the speed increases with height.

Can wind make sound travel further?

Yes, wind has an effect on the speed of sound, and this effect has interesting ramifications for the propagation of sound outdoors.

How far does wind carry sound?

By itself, wind has very limited effects on noise propagation, other than to increase or decrease the speed of sound. At short distances, up to 50m, the wind has minor influence on the measured sound level. For longer distances, the wind effects become appreciably greater.

Does wind affect frequency of sound?

Wind has essentially the same effect as an increase or decrease in sound velocity. If the crests are moving with the wind (in the same direction as the wind), then sound velocity is effectively increased. This has two competing effects on the perceived frequency.
