I think we should find the way not to specify fixed numbers, but I realize it's almost impossible if we want to keep the SC testable; also the 20 db threshold is a fixed number, but in that particular case, I feel that it's a reasonable compromise.

It is level 3 but… I wonder if we can figure a way to get what we want without catching so much else that it would be ok to leave out.

Audio content does not contain background sounds OR the background sounds are at least 20 decibels lower than the foreground audio content with the exception of occasional short sounds. [V] </current> <proposed> 1. Audio content does not contain background sounds OR the background sounds are at least 20 decibels lower than the foreground audio content with the exception of occasional short sounds. (where “short” may be defined as less that 10 seconds and “occasional” may be defined as occurring more frequently than once every 10 minutes.) [V] </proposed> In an attempt to make our guidelines testable, I chose 10 seconds as the as the threshold for the word “short” to allow for what the movie industry would describe as an airplane passing overhead or a bomb exploding. I chose 10 minutes as the threshold for “occasional” because I think any more frequency than that would be quite distracting and difficult to follow [Messaggio troncato.
