i was just thinking abt ur quest...... now when u go past a pole or a tree..the thing is that ibelieve that a pressure difference is createdwhich in turn produces sound waves therefore more the speed more the pressure difference hence more sharper is the sound...
|
u can ask any query u wan

when you pass by a pole or something with a speed you actually create a disturbance in the surrounding air medium which generates wave pulses. more the more the disturbance.hence more clearly the sound is heard.

Just a guess, but every object has a frequency of its own, so when u go nearer, maybe due to the slight diference in the frequency changes and as vatsasm.co said, due to the disturbance in the medium, the sound reaches us!!!! :-??

that only i m not able to make out that how it creates a sound ..... ..acc. to me frequency would not be the just only reason for it..

obviously it would not be the only reason, i said it was only a guess, there might be the influence of pressure diference, as someone already mentioned, and the doppler effect enhances the sound as u approach nearer.

are yaar, when you just get by side of it, the air motion( included probably in aerodynamic educational books) would look circular, that might hardly blow through tangential or other( not in normal which is a limit for the distance) angle with your ear thus making a sound. I guess pressure diif is couse but there is no frequency diff as the same sound is not audible by a stationary observer
