Hello All,

Since last Sunday night (9th October), I've heard a low frequency hum.
It's especially can be heard downstairs. If I go outside, it's less by
the house, but moving away the house, it's inaudible.

The only two nights it wasn't audible was last Wednesday and Thursday night.

Could the atmosphere be increasing the range of nearby factory noise.
The nearest factory is about 2 miles away.

I experience similar phenomena, and am undecided whether it is tinnitus, or
the much publicised low frequency hum, which seems to be prevalent in some
parts of the country.
It has been ascribed, variously, to eddies in gas pipes, factories, nearby
diesel generators, or deliberate LF propagation.

Look up "Low Frequency Hum" on the web - some quite surprising information
is available.

Thanks Natsman, I'm pretty sure it's not tinnitus, because I've had the
condition for the past 30 odd years. Tinnitus I have can be heard
wherever I am. The low frequency hum, seems to be resonating the
brickwork of my house, as it's inaudible if I go outside and move away
from the house.

For the first few nights I couldn't sleep properly, but since then, I've
just took no note of it.

This is a worldwide but fairly localised phenomenon that's been
documented for many years but, to the best of my knowledge, never fully
explained.

Many people have experienced it in my home town of Largs, Ayrshire. It
really is an environmental health issue there as it seriously affects
the well-being of the more susceptible people. Do a Google search on
"Largs hum" and you'll find a lot of stuff.

This site documents a number of UK occurrences:

Surely it's simply ducting when a strong inversion (as we had recently
until today) traps the noise?

I am about 4 kms from the busy A505. I never hear it unless the is an
inversion. Equally, aircraft flying above the inversion are heard less
in these circumstances.

Presumably a "hum" is a combination of various, normally undetected,
noises? It certainly must be annoying, but the reason seems fairly
obvious.

Next time you get a cool unstable Polar airmass, I bet you don't hear
the noise as badly.

A friend who suffered from "The Hum" told me that it disappeared once
he'd taken blood-pressure reducing drugs.

I sometimes figure I can hear it in the small hours when it's very
quiet outside. I sometimes wonder if it's the fridge and some kind
of resonance effect, though I've never actually been bothered to
go downstais to see if it's on!
Can it ever be *totally* quiet anyway in an urban location?
I would have thought that distant traffic at least would pretty much
always be audible once other nearer sounds have vanished.

I've noticed this for years in every property I've lived in!

It used to drive me to distraction. I thought about the fridge being the
cause, but even switching off the household electricity supply made no
difference. I used to go for walks at night to see if I could find a
generator running nearby!
The doctor wasn't very sympathetic, and thought it was tinnitus. Blood
pressure normal. I just had to get used to it. Many nights can pass with
no hum, then it'll return for a while. The wife thinks I'm going mad. She
probably has a point....
