A low hum in Australia, Canberra
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 doesn’t pick up what I hear. Whilst in the middle of that process I’ll then hear a car approaching far off in the distance and it picks up those sub-100Hz frequencies with no problem!
I do still wonder about ototoxicity as a culprit. I was a smoker for many years which certainly wouldn’t have helped.
What they reported
First noticed: 2016
Pitch: 69Hz
Loudest: During the night
Where: Indoors
Symptoms: Ear discomfort (pain, fullness, throbbing), Sense of vibration, Anxiety
Changes with weather: No, other than when it’s rainy or windy then the respective increase in ambient sound tends to drown out the hum.
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…

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.
