Not conclusively, I guess, but it's there at any time the conditions are correct (ie, a fan moving air somewhere in the apartment, and otherwise silence).
It, however, sounds nothing like an acoustic leakage sounds, I'd describe it more as envelope-shaped white noise then filtered to a range of 'high' acoustic frequencies (maybe 8-14kHz, but I'm guessing); whereas structural leakage of audio has a different profile more in line with being low pass filtered.
I have heard leakage audio from the only neighbour that it COULD be from, of their TV and Radio audio, and that has the normal low-pass sounding profile as you'd expect.
So while I can't rule out that it could be leaked audio, it 'doesn't sound like it' to me.
- blincoln 3y agoI grew up in a house that was next door to a radio rebroadcasting facility, and we could definitely hear the radio station coming from the walls of our house sometimes, e.g. even their station identification so there was no ambiguity. I assumed it was the house wiring (mostly knob and tube) acting as an antenna. I'm reasonably sure that was AM, though. Was the sound you heard like either of these? https://www.youtube.com/watch?v=uo9nGzIzSPw https://www.youtube.com/watch?v=uo9nGzIzSPw https://www.youtube.com/watch?v=b9UO9tn4MpI https://www.youtube.com/watch?v=b9UO9tn4MpI
