I made recently recordings from various elevations with white noise signals in an anechoic room. Elevations were from -15 to 45 degrees and azimuths from 0 to 355. The recordings lasted about 5 hours. I noted clearly that the noise signal from higher elevations frequently seemed to have higher pitch, especially if azimuth was about -45 or +45 degree. However, this can not be generalized because I have a high-frequency hearing loss. It would be interesting for me to know if someone has observed the same. In literature of spatial hearing there is described an inverse phenomenon when one hears a pure-tone from a speaker in front of him. Then the location perception is depending from the frequency of the pure-tone. This has been interpretated as 'directional bands' of the head-related transfer functions and is described by Blauert, 1972 (and 1983). The phenomenon seems to be restricted to pure tones because these are very difficult to localize. kind regards, Johannes 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
