Sound does move air and thus makes wind. We "feel" the movement with our ear. The tympanic membrane of the ear is moved back and forth in response to air movement, causing the bones of the inner ear to move and thus transfer the "sound" (air movement) into the cochlea which turns this into what our brain interprets as sound. We DO feel the wind.
If you hold a candle in front of a large loudspeaker the flame is blown away from the cone. This must be because the movement of the cone, back and forth manages to generate a current of air at the same time as producing the sound, which is just longitudinal vibrations. This may be because of the flexing of the cone. BUT they are two separate and distinct effects.
It's nothing fancy. There is just a current of air caused by the fact that the loudspeaker cone is of finite size and you are in the 'near field' of the vibrations. The flame just leans away from the cone (and the smoke drifts away too). This effect only occurs quite close to the speaker (10cm or so) and for very loud sound levels; the cone acts like a fan. When the cone moves forwards it pushes air forwards (momentum transfer to the air on its surface); when it moves backwared, air flows from all around into the vacant space because the pressure all around is higher. This is a circulation effect which dies rapidly with distance (within less than a wavelength, probably) ; a near field phenomenon.
Well, you know me. If there's a simple, classical, explanation for a phenomenon then I'll go for it. There are enough neat explanations without running off into Quantum Mechanics in the first instance.
I'd like to know how they got the picture of the diffraction pattern in the first post; is it smoke or precipitation?
Does sound move the air it travels through ?...if so....if the sound was loud enough...would I ' feel ' it against my face as a breeze ?
