Well, yes, but please bear in mind that all of those audibility results are based on three unrealistic assumptions: 1. Unbearably loud sounds. 2. Absolutely quiet room. 3. Sine waves (that nobody listens to). I.e. they are the worst case in many aspects. I keep promising myself to start working on (3), and I got some high-quality recordings of typical room noise for (2). But for several days, when I come from work, I start wasting time by watching videos or chatting instead of working on these problems. Sorry for that. -- Alexander E. Patrakov
