A search for a good citation on the relative effects of SNR & overall level for perceiving speech in noise
I would be grateful for some references to work showing what we all know
to be true -- that the primary determinant of performance for speech in
noise for audiometrically normal listeners is the SNR, depending little
or not at all on overall level (at least over a fairly wide range of
moderate levels).
For those interested, this is a nice study on the extent to which speech
perception is invariant across level for a wide range of levels:

P.S. I hope I am not opening a can of worms here!
P.P.S. I have done some searching but cannot find anything relevant.
