Re: World's Most Reverberant RoomDo you have some part numbers? That's a pretty low self-noise for direct measurement. I'll stick with the extrapolation story, although I do question the .1dB resolution in this context.Signal averaging, although a very useful class of techniques for many low-noise measurements, doesn't help you here as the statistical properties of the signal are not sufficiently distinct from those of the noise. (Oh, and I do know how dB SPL is defined, the negative value wasn't the point. This is an AUDIO forum.) --Frank
