The discussion revolves around an unusual alarm signal experienced by a user named Duncan, who reports hearing a continuous beep from various electronic devices in his home at midnight. Participants explore potential sources of the signal, including radio-controlled clocks, smoke alarms, and other electronic devices, while also considering the possibility of reverb complicating sound localization.
Participants do not reach a consensus on the source of the alarm signal. Multiple competing views remain, with some suggesting electronic devices as the cause and others proposing alternative explanations.
Participants note the difficulty in locating high-frequency sounds and the potential for misinterpretation of the source due to acoustic properties in the environment.
This discussion may be of interest to individuals experiencing similar unexplained electronic sounds, those interested in sound localization challenges, or anyone curious about the behavior of electronic devices in residential settings.

The guy in the video seems to be an audio engineer who has lots of mics laying around. I was looking for a practical solution that the OP could apply.jedishrfu said:I think the video would be too long if he used one mic at a time with a cone. :-)
A.T. said:That's great, but uses a lot of equipment.
I wonder if one could use some simple listening cone and point it in different directions, to estimate the source direction based on the volume changes.
I tried and you can get to the right room (or maybe better) with a cell phone and a sound level app...if it is in a room. If it is in an above/below crawl space it may be more difficult to localize.jedishrfu said:He said in the video he went to the store to get these mikes.
You could probably do the same thing with two mikes and narrow things down in a binary search sort of scheme.
