A low hum in Australia, Batlow
low frequency 'thrumming' seems to be modulated around nication2 hz The sound seems directional, around due North, it is just as loud inside as outside - there are 330kv powers lines due north of my house, around 700 metres away - I theorized it could be a phase shift in the power lines, as the hydroelectric generators have a lead/lag according to power load, so vary from 50 Hz (nominal) which would explain the beat frequency of 1 Hz.
Low droning sound. From a scientific perspective, mine clearly must be an internal ‘perceived’ hum of sorts. I’ve used an external microphone with an FFT plot / spectrograph and it simply do…
Very low frequency that seems to vibrate in my whole body. Continuous though much worse at night and I feel too “ uncomfortable” to sleep. My “theory” is that noise relates to very small vib…
Distant idling diesel engine, stops when I yawn or if a sound is made I played an audio 'subwoofer test' online at onlinetonegenerator.com and after I stopped when it got too low hertz I too…
Low frequency hum about 35-40Hz. Sounds mechanical like an industrial air conditioner. Mostly soft monotone but sometimes loud reciprocating like a pump or motor. I have turned off all elect…
A non rythmical pulse/vibration/ utter torture Nice to see the shaking the head one, im not the only one who looks crazy. If i shake my head at just the right speed the noise disappears? And…
Humming/ rumbling in ears that can last months or come and go over days. Extremely stressful after all tests reveal nothing wrong. Causes stress and anxiety. Feels like an invasion when you …
Like a constant low-frequency humming noise, like an idling diesel engine at around 67 Hz. Quite often very invasive. The local environmental authorities ran some audio recording with a clas…

Has this happened to you?
Write it down while you still remember the details. We will look for the others.
If this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
Nothing is tracked back to you and nothing is sent on your behalf. The link is just the page you are reading.
