AI Article Synopsis
- The study examined how female distracters affect the ability to hear a target female talker, starting with a baseline where both were presented from the front.
- When the distracters were presented from behind the listener with slight timing differences, the listener experienced less informational masking.
- The greatest relief from this masking occurred with a timing difference of around +/-2 milliseconds, leading to a peak improvement of approximately 3.5 dB, while energetic masking was reduced only with very small timing differences of +/-0.5 milliseconds or less.
Article Abstract
Informational masking of a target female talker by female distracters was measured with target and distracters presented from directly in front of the listener as a baseline condition. Next, it was found that if the distracters were also presented from directly in back of the listener, advanced or delayed by a few milliseconds with respect to the distracters in front, release from informational masking occurred. Release from informational masking was found for all delays within the Haas region of +/-50 ms, with peak release of about 3.5 dB. This peak occurred for a delay of +/-2 ms and it was shown to be the result of delay-and-add filtering. Release from energetic masking was also found, but only for delays of +/-0.5 ms or less.
