    Wild guess, atmosphere conditions.

    I'm pretty sure the proximity effect goes lower than 200 hz. Poor mic'ing on a hi hat will make it sound like a dust bin lid and will have frequencies below 200 hz that are present. It wont be a tone though it will just be random frequencies occuring simultaneously.

    I haven't read the article but low frequency wavelengths are fucking massive. A 100 hz wave is roughly 11.3 feet long at 72 degrees farenheit. So higher frequencies lose intensity faster than lower frequencies. Also higher frequencies are highly reflective so they probably just bounce of the diagphram. Lower frequencies move more air, imagine someone blowing in your ear. A mic is basically an ear.

    I should know the reason why though. I need to start reading again!

    even removing elements like the atmosphere and acoustics it still happens... perhaps the engineer that said it happens in 200hz to 600hz means thats where it mostly has it's peak?

    You can't remove the atmospheric effects mate. Otherwise it would be a vaccum. Sound needs a compressible medium in order to propagate.

    You know what I mean, I just want to understand how the proximity effect relates to microphones
