What do wet brakes sound like?

How does weather affect an outdoor noise study?
In most situations that we encounter, the residents are much closer to the noise source, and the affects of wind, humidity, and temperature are insignificant. That said, there are other ways that the weather can alter a sound reading, even if the measurement location is only a few hundred feet from the noise source.
Why is traffic noise louder in the daytime?
This means the sound would be louder and you could hear the traffic noise from farther away. During the daytime it’s very hot at the surface, and sounds refracts the other way, up into the atmosphere, and away from our ears.

What is the effect of wind on sound?
Wind’s effect is more about distortion of sound. As a sound wave propagates, or moves, through the air, some pieces are accelerated and others slowed down as it meets wind. On a windy day sound waves won’t propagate as one distinct wave, so it will be indistinct when it reaches your ear.
