This is the latest AES paper submission from Dr. Floyd Toole. It deals with the Measurement and Calibration of Sound Reproduction Systems.\n\nThe following discussions will embrace both large and small venue sound systems: cinemas for public exhibitions, home theaters and stereo systems for private entertainment, dubbing stages for movie sound track creation, and recording control rooms for music production. The physics of sound creation and propagation are the same in all of these, as are the perceptual processes of listeners, so substantial\ncommonality is anticipated.\n\nDr. Toole has made this paper available to the public for FREE.\n\nPlease download and read it and discuss here. If we generate a good discussion it may inspire some participation from the man himself. We can all use this as a great learning experience so I welcome lots of input.
