Subject: static spectral alterations From: beauchamp james w <j-beauch(at)UX1.CSO.UIUC.EDU> Date: Thu, 3 Oct 2002 11:42:36 -0500Does anyone know of any peer-reviewed published papers on the perceptual effect of static spectral alterations, such as might occur due to room or speaker responses, on musical or other types of sounds? The perceptual effect could be measured in terms of sound source recognition, discrimination with respect to original unaltered sources, or judgements of similarity to the originals. The only paper I know of that touches on the subject is by Arthur Benade (J. Audio Eng. Soc., Vol. 33, p. 218 (1985)). His conclusion seemed to be that we can only recognise musical instruments reliably in rooms that "average" sound spectra when several notes are played. He played down the importance of time-varation of spectra. Jim James W.
