Most single-pitch sounds aren't directional inside a room, just move your ears around a few feet and see how many different directions you hear it from. You're hearing the standing wave pattern set up between the walls, and 'loudest is where it's coming from' gets fooled. I once spent several hours trying to find out why my server had started beeping for a minute at midnight, quite loudly. Cron and anacron seemed innocent, but *something* was causing it. I tried software disabling the internal speaker, no good. Eventually I tried standing in front of the server at the witching hour, with the door open, hoping to get a directional fix on the beep. I did... it was coming from the nearby weather station, which unknown to me had two alarms, which were trivial to enable if you hit the wrong button when setting the barometric pressure... -- Joe -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
