I posted this in the thread "Lightning" (see below) but as this has been a
major puzzle for me for a long time I have just realised this is the perfect
place to try and get to the bottom of it. Especially with you in here Gary!
Have you heard these noises?


For a long time in the seventies and eighties in Torbay, Devon there was
sometimes a long deep throaty rumbling coming from the sea. Deep, regular,
lasting perhaps 7 to 10 seconds with
perhaps 20 seconds between rumbles. Very deep, almost infra-sound. There
was talk locally of underwater blasting turning berry Head into submarine
pens. But I never went for that really. There was never any lightning at the
time. I can remember many summer evenings listening to this. Many people
heard it and thought nothing of it, but it has always puzzled me. Nowhere
else have I heard this, and never had a proper explanation. I have thought
of many theories, both natural and man made... but none have satisfied all
the clues...

Military gunnery ranges?

There are a number in S and SW England, including some marine ones.

It is amazing how well low-frequency sound will travel. I have heard the
sounds you describe from my location just west of Southampton, and these
almost certainly have come from gunnery ranges in Dorset, west of
Bournemouth. Only a week or so ago there was a thunderstorm with brilliant
lightning but delays of getting on for 2 minutes until the thunder arrived.
News reports told of lightning damage on the Isle of Wight, the nearest part
of which is about 15 miles from where I live.

..... best idea so far Yokel! Yes, there are ranges out in Lyme Bay and I
believe gunnery on the cliffs too further down the coast. At 5 seconds a
mile 2 minutes that's well over 20 miles...

Les and all,
Having lived in Devon for about 15 years, I've heard this noise on
many occasions, and it's Concorde (the air France one in S Devon)
heading up the English Channel. At supersonic speeds, it generates a
sonic boom, and due to its height, the boom is reflected by the sea
back up to the tropopause and back to earth again, causing a series of
booms. In N Devon and Cornwall, you can also hear the BA Concorde as
it slows down as it heads up the Bristol Channel. I'm not sure if this
is the same noise that you refer to, but it sounds like it! Living in
Reading now, I hear Concorde as it accelerates westward
overhead...subsonic, but only a few thousand feet up on full
afterburner, it's a rather impressive noise!!

cheers,

Paul K.

Hi Paul
Yes! I Remember that one. My family named it "The Nine O'clock Boom"
It was a rather impressive noise like you say, it mostly scared the living
daylights out of me, especially on foggy nights!
I dont hear it so much now.

....... yes, used to Concord going over.. definitely not that though. Living
in Paignton and Brixham, you get very used to the booms in the evenings.
This was different, concord gave a signature double boom due to it's shape.

Les,

There is a local effect up my way that hasn't been explained.

Basically, a low rumbling that comes and goes if you live on the west side
of the Malvern Hills close to the railway tunnel that passes through it.

It doesn't occur when trains pass through or seem to be train related at
all.

It has been suggested that it is caused by the wind either blowing through
the tunnel or (my favourite) blowing across the tunnel entrance. Bit like
blowing across the top of a wine bottle, just bigger. :-)


I've heard also heard of an effect in (very sketchy, long time ago) a
coastal area in Mexico. Low rumbling in certain weather. Turned out to waves
pressuring trapped air in an almost totally underwater cave system. Bit like
a huge tuba, the brass instrument. Saw a program about it years ago and
turned out some people could hear (and drove them mad) and others couldn't
hear it at all. Some could hear it up to ten miles away.

Maybe something like that ?

Cheers

Ian

Paul,
Did it shake/rattle your doors and windows ? The effect here was so strong
once that I honestly thought someone was trying to break in !

Jack Harrison :
The Concorde rumble could be heard when I lived in a very remote part of
Gloucestershire many years ago. Apparently, it has even been detected as
far away as Scotland.

The strangest thing about hearing that rumble was when I used to go walking
with my dad in the woods of an evening in south Wiltshire. You knew when
you were about to hear the concorde boom, because the pheasants started
up a second or two beforehand. They obviously sensed something we couldn't.

Not heard concorde here for some time now, but used to hear it regularly
in late evening up here in the Welsh mountains.

Jon,
It did! The letterbox rattles, any door left just ajar would sometimes
open, and once I felt a kind of compression on my chest!
