Subject: Sound Attenuation From: "Michael S. Gordon" <mgordon(at)UTM.UTORONTO.CA> Date: Mon, 24 Feb 2003 15:53:16 -0500--=====================_1341062==_.ALT Content-Type: text/plain; charset="us-ascii"; format=flowed Dear List, A colleague of mine is interesting in running a monaural sound localization experiment. It is important for this experiment that he present his stimuli from a free-field speaker array, so headphones can not be used. Our question is what would be the most effective technique for attenuating the sound in the non-listening ear? The sound stimuli will be 50Hz - 8 kHz and 40 - 70 dB. Any information you have on how best to accomplish this attenuation, references, and advice would be greatly appreciated. Thank you in advance, Mike -- Michael S.
