Hello All,
I am looking for references for appropriate techniques for measuring
reverberation time of a medium sized room (approx. 40'x40'x20'). 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
