I was wondering....

"Masking" is defined by the ASA as both a "process" and an "amount":

"The amount by which the threshold of audibility of a sound is raised by
another  sound."

I may be missing something here, but can anyone provide a (sensible)
sentence in which "masking" is used according to the latter definition?

I don't think "20 dB of masking" counts - isn't this like saying "20 miles
of driving"?


Cheers, Chris
