Does anyone know the experimental standard deviation of a critical bandwidth of hearing? A few years ago, someone told me it is on the order of 50% which sounds too high to me. I am not picky about which type of measurement is used, but I am working with the Bark and ERB scales, so classical narrowband masking and notched-noise based definitions would be ideal. Since I will be mentioning this in a paper I am revising for the IEEE SAP, it would be ideal to have a reference, but a "private communication" would also work. Heck, it can even be an "anonymous source", I suppose. Thanks for any info, Julius Smith CCRMA, Stanford Email to AUDITORY should now be sent to AUDITORY(at) LISTSERV commands should be sent to listserv(at) Information is available on the WEB at
