In = specific, number and position of loudspeakers, level and type of signal. = Does your technique and stimuli vary depending on your question of = interest (e.g. absorption characteristics versus effects on sound = quality or speech intelligibility)? We are interested in speech = intelligibility by the way. I have ordered an IEC standard that = supposedly describes a "standard" method for measuring reverb times when = examining the absorption characteristics of materials. Any thoughts are = appreciated. Thanks, Ben Hornsby ------=_NextPart_000_0055_01C178E4.070C2E80 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content=3D"text/html; charset=3Diso-8859-1" = http-equiv=3DContent-Type> <META content=3D"MSHTML 5.00.2919.6307" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV>Hello All,</DIV> <DIV> </DIV> <DIV>I am looking for references for appropriate techniques for = measuring=20 reverberation time of a medium sized room (approx. 40'x40'x20').
