"Breathing" of the air

So typical. Always comes down to money with mean spirited types...aka Cavemen....

Mean spirited?

Allow me to point out your pro hot air generator remark which precipitated this exchange.

Perhaps you forgot about it during all the excitement in study hall.

Teacher's pet are you?

My perception ... air on its own we cannot hear, but can be heard once a sound excites air in a space and it reveals the characteristics of the acoustic environment that the sound was made in. I believe this to be the sound of air. I also think not just the high frequencies but all frequencies high-mid-& low are telling of the sound of air.

best,

Tom summarized is correctly. It is the medium displaced/excited in which sound is generated (vibrations generated by instruments)is what we hear. As a Kind of 'halo' around main notes- fundamentals and harmonics. Room acoustics is another entity that may impose its own signature on this 'halo' by allowing it to throughly develop or reduce it or make it dead. I am not sure but you would think you could measure the air disturbances as a change in air pressure- compression and decompression. I am no expert in this but an answer to this or confirmation to this would be to know how the anechoic (sp?) chamber is designed.

What exactly is anechoic chamber? a Room designed not impose sound signature due to room boundaries or and that would you still hear pure 'air' or 'halo' in this chamber?
