Determination of Multiple Sound Sources

Abstract

We have completed the final construction of the sound-deaden listening room and the digital library of stored words, numbers, and letters, from nine English speaking males. We conducted pilot experiments on 20 subjects listening to one and two sound sources at a time. The results of the pilot experiments indicated that the sound room was well calibrated and allowed us to determine that a few of the words, letters, and numbers should be recorded. In addition the pilot experiment suggested a few modification to our protocol. The new utterances have been recorded, the protocol modifications made, and a new set of 10 subjects were tested. The results from this additional set indicated that we had a good listening room, set of utterances, and procedure. From October until January of 1993 we will test the headphone listening protocol making adjustments were necessary. We plan to collect data in the full experiment starting late January 1994.
