Have you ever regretted ABXing? Reply #50 – 2010-11-08 16:28:44 Quote from: Arnold B. Krueger on 2010-11-08 13:00:47No, data about totally empty rooms is *not* relevant, at least until we start generally making recordings in totally empty rooms. I think there's only one piece of music that could be recorded this way. It was written by John Cage, if memory serves. ;-)There are also quieter rooms than those. I think one of them is in the Carlsbad Caverns in New Mexico. If data is going to be relevant it has to have a useful level of generality.Do you have any reason to believe that the sounds made by the musicians are universally sufficient to mask the dither noise? After all, two of the Meyer-Moran subjects were able to detect the 16 bit noise floor with the peak level set to 115 DB. This despite the listeners' self noise (how's that for a new term?) and the possible presence of others in the room (I don't know enough about the experimental details to know if others were present).
