Stc sound attenuation
WebSTC + NC = 96 + 10 log S -10 log A 1 - 10 log A 2 (2) Complete inaudibility is a more stringent requirement than speech privacy by about 10 db; hence the base figure in Formula (2) is 96 instead of 86 as in Formula (1). As before, an additional increase may be required for higher than normal speech levels.
