Noise

Low frequency noise can be a rumble or hum and can be associated with electrical sources, heating systems, fans or machinery such as pumps. They can be difficult to deal with under statutory nuisance legislation due to the low volume.

On occasions such noise can be linked with tinnitus or due to people having a sensitivity to low frequency noise. However in most instances, no sound can be detected that could account for such disruption.

It may be worth speaking to your neighbours to check if they can identify the noise in their homes or outside. You could also test your appliances by switching them on or off. Or alternatively, if you're the only person who can identify the noise it may be worth seeking advice from an audiologist regarding your hearing.
