Unknown noise at night? (humming/twang)

Anonymous user 01/03/2024 - 2.50 PM

We live in a 1st Floor apartment. We have a neighbour above and shop underneath (which sells carpets). We have no direct side neighbours. Our spare room and bathroom has a wall which separates them from the communal stairwell. Over the past 2-3 months during most evenings from about 8.30pm until gone 9am the next morning a noise starts up like a humming/winding noise. It gets faster and faster ands winds up so much it then suddenly stops. Then follows a twang like noise.. This goes on all night every 45 minutes approx. Some nights is quieter than others but has caused us so many sleepless nights. The noise is much louder this end of the flat and the electrician checked electric boxes and they seems OK. They also said it is not upstairs fan. I have Googled and lots of similar sounding issues relate to water pipes. I have no idea what runs where. Also why is is only going at night and on some sort of timer? I tried to record the sound which is hard on a mobile but if you listen with headphones and turn the volume loud you can hear it. Especially when it suddenly stops. Then a few seconds after it stops you hear the 'twang' noise. https://www.youtube.com/watch?v=WH2bqWp9-c4

Are you a tradesperson and able to answer this question?

You say there's a carpet shop below? I'm guessing there will be air conditioning in the shop below, so I would point to that. As the air changes the sensor kicks in and turn the motor on/off all day everyday Regards K
