Strange rumbling sound in Donnybrook

ctopher · 25-11-2020 9:53pm #1

So perhaps a strange question, but the last few weeks there has been a loud periodic rumbling sound coming from the sky. It sounds vaguely like a generator crossed with a spinning washing machine. It lasts about two seconds and repeats 5-10 times and occurs every hour-ish.

It’s definitely coming from ‘above’ suggesting it’s widespread.

It’s quite loud, waking us up at night. Has anybody got any clue what this might be?

Pardon me.

Sprouts.

A flying object perhaps.

Blasts of hot air coming from RTE studios.

Quite possibly a generator in a power station or the engines of a ship.

Lockdown means less noise to drown them out.

If its night time, it could be from miles away. Noise travels further at night.

Possibly something at the Bus garage?

+1 or maybe they're testing or servicing the pumps (OP said sounds like a spinning washing machine) in the tenders down at the fire station. Work that would make sense to do at night when there's less demand for the fire service.

With all the local pubs and restaurants closed, it's most likely coming from either the fire station or the bus garage.

It wouldn’t be from the air consitioners in the 4 Seasons (or whatever its called now?). They might be blasting them on briefly in all rooms to avoid them becoming musty smelling. Apparently that, and daily flushing all the loos to prevent marshy smells in estate hotels are becoming covid pre-requisites.

They can do all that in the daytime. In which case they wouldn't be waking up the OP at night.

AC is cheaper at night

Thanks for the replies everyone. Not sure the answer is here yet.

Can’t be the hotel, nowhere near, same for bus garage.

Sounds more like a generator but would need to be huge! When you’re outside you can’t even tel the direction it’s coming from.

Maybe it’s aliens ðŸ‘½

You've just found proof you're living in the matrix.... congratulations Neo!

I can think of two possibilities: sounds from Dublin Port - only a little over 2km as the crow flies and there are a lot of mechanical noises from there. The other is the Poolbeg generating station (AKA the Pigeon House) - again a little over 2km away and there's mechanical noises from there. In both cases, the noise travels further at night and I've heard noise from one or the other when in Donnybrook.
