acoustical

There were also times when the /best/ sound really was a tube amp with separate power drop, acoustical treated wall, and the whole shebang.

\n\nIf you read the intro to that paper, it's very clear that it was acoustical noise that was measured and likely to be caused by a blast furnace.

The only thing that makes loudspeakers viable really is our uncanny ability to make sense of room acoustical distortions.

Acoustic couplers are designed to minimize any acoustical impact of their use to avoid the exact acoustical problems you'd have transmitting across a room.

Why would it be understandable that some employers would not believe that he is a capable black acoustical engineer?And even if they did, wouldn't it take maybe 5 minutes worth of correspondence to figure out if he was or was not?

Unless you are saying there is rampant racism in the acoustical engineering industry to the point that he would not even advance to a correspondence level with a hiring manager based soley on the fact that he is black.. Which I would doubt.

The fact remains that the modulation and signaling protocols developed for use in modems were designed within the constraints of electrical transmission across miles of copper wire, not through sounds waves in an unknown acoustical environment.
