Is there such a thing a audio distortion in nature

   I think a sine wave of high enough SPL becomes more saw-tooth shaped over distance. This is because sound travels faster in higher pressure air so the high pressure parts of the wave end up skewing in the direction of the wave. Apparently this is noticeable in situations with loud SPL being heard from a distance such as rockets taking off and thunder.

	The sound of one hand clapping is pure distortion.

	Yes of course. Nowadays we have constant, whether it be a motorway like the m25 in the distance or a waterfall in a jungle. It's there and there is no getting away from it. Edited by KidCreole - 22 September 2014 at 4:54am

	24.8.1 Mother Nature’s Way There are in audio and acoustics both natural and unnatural distortions. An example of a natural distortion is harmonic distortion because we hear harmonics in nature. An example of an unnatural distortion is print through on tape recordings where we hear the echo first followed by the desired sound. This never occurs in nature, thus our brain is extremely sensitive to its occurrence. So it is with “boost filters.” Sound System Engineering 4e - Davis, Don
