Attenuation is normally not frequency-independent, unless it is designed 
to be so. So pretty much anything has an highpass and/or lowpass aspect to 
it unless you compensate it or you're just lucky...

I can't imagine studio mics doing things that favour the bounced-off waves 
at the detriment of the direct sound...

Uh, wouldn't air turbulence would be a consequence (side-effect) of the 
filtering, not the cause of it?

In the case of sibilants, there is a turbulence going on inside of the 
mouth, but once it comes out of the mouth, it becomes just noise. Pretty 
much any large-scale natural [noise~]-like sound has to be generated by 
some kind of turbulence. Turbulence is normally a generator of noise, 
isn't it?
