Never heard of this before (assuming this is country specific), but I would like to know more about why/how this white noise sound is apparently easier for our ears to pick up on. It doesn't automatically make sense to me, and I don't get how it's easier to place the exact location of the <b>PSSH PSSH</b> sounds either. Would love an explanation or a link to further info on this.,(reply>), It doesn't reflect as easily as beeps.
