Re: That hiss

["Volker Widmann" <>]

This a an interesting thought.....
I recently read somewhere that even in recording studios there usually is a 
background noise of 20 dB.
I wonder where that comes from....

But seriously, can anybody verify this?

Maybe this is not a new discussion, but is there really any acoustic 
environment without any noise?

Are the mic self noise specs in relation to zero noise or to the the background 
noise of a laboratory?
