Its like hearing a high flying plane but the sound isn't fading as a plane would as it passes by. Its a constant humming almost far away siren sort of sound. There is a alcohol bottling company near by, which sound an alarm if there are any spillages etc. But this is a varied siren and it very audible if you open a window or door. But this hum doesn't vary in tone and I couldn't hear is clearly after opening the door. And my mother cannot hear it.

like hearing a cross between a siren and a refrigerator, or when the lightbulb or wall electrical makes that weird noise it does, except coming and going rhythmically like an air raid siren.…

It humming sounds like a low trumpet sound or rather like a low calling sound a whale make. That sound is about a slow 10second then pause with a low buzzing or rattling sound of almost 10 s…

A low hum with a specific pattern of long and short hums. Hear it mainly out of my right ear. It's not always constant. Some days I don't hear it at all and other times it's very loud (to me…
