Take a two sound waves: for example let us spread them at both poles of the human hearing spectrum. The low frequency at 20Hz and the high at 20,000Hz.
Which sound wave carries with it more energy?
It is said that sound travels at 343m/s, is that true of all sound in the air medium, meaning will the low frequency wave arive a location X before the high frequency one?
This question stems from a recording I did with a microphone, I placed the microphone in my pocket at waist level, upon a later listening to it recording, it show that the higher frequency are about 5-10dB lower than the low freqs, something that was not apparent during the recording while I was listening at ear level with my ears. (at ear lever there was a clear path from the speaker to my ear, and at the recorder lever there where a bunch of sweaty bodies obstructing the way.)
What can be attributed to this phenomenon? What effect is the mass of bodies having on the propagation of the sound?
