Air Source Heat Pumps (ASHP).

[shanered6]

That type of noise is bloody annoying other people come to your house and say.....Oh i dont hear it much .... but its when the daily routine noises stop and you settle down thats when it gets bloody annoying !!! 
we have a quarry about a mile away ( apart from the bloody reverse beeping ) its not to bad !..... but every once in a while they use a pump to bring water from from a burn just below the quarry to replenish the wash plant , now i dont hear it in the day but when yo go to bed you just hear this constant humming which just drives you mad  and once you started to hear it it seems to get louder and louder even though its not ...... theres nothing worse !

Good thing you don't live in Australia at the moment, all the noise from all those Air Con condenser fans spinning with their blazing temperatures.

I can't hear my aircon unit as the doors and windows are normaly closed to keep the house nice and cool.

I think when I was in the UK it was louder listening to the Pom's moaning about the cold, wet and dark and not riding their bikes for months.

3db is double, so if 42 is the limit that makes 52-54 16x louder.

It doesn't work like that. 3dB is double the power, but your ears don't respond to power differences in a linear way. Very approximately it takes a 10dB difference to perceive that one noise is twice as loud as another. It gets more complicated because loudness is a subjective term and also it depends on the type of noise (frequency, repetition and so on).

But anyway back to the issue - according to my 5 minutes of Googling, you can install one of these heat pumps without planning permission under the rule of 'permitted development'. If you do that, it must meet a bunch of criteria - one of which is that the noise level has to be 42dB or less. So maybe the best way to tackle the problem is to put in a planning complaint.

BB sorry about your noise issue. I have issues with a neighbour. He invited an earthmoving contractor to fill a gully on his land. The contractor gleefully accepted his invitation. So now he has a 5 year consent to fill a 190,000 cu m. Add 50% for compaction then divide by 10 cu m to give an approximate number of truckloads to fill it. A truck goes in and the back out, then the bulldozer starts pushing the dirt around. I told council its a business, they said no, its an activity. I said its too loud they came and measured the noise. 48 constant with peaks up to 56 dba. Council says l'm lucky, he can go to 85. I love good news. 

I do have a tree and a chainsaw. Am told early Sunday morning is a good time for making matchsticks
Good luck with.it.mate.....stay calm or you lose.

Wait,wait,wait, one presumes his heat pump pushes headed air from outside into his house.
Nice bucket of fish heads and frames placed next to your fence might get his attention.

Nice thought Col, but heat pumps don't work that way.

[Kiwifruit]

Could work better putting them in the neighbours letterbox then ??

[KiwiCol]

Under bedroom window works well, also biffed under the house, which also has the added bonus of every neighbourhood cat hanging around.

I like the fish bodies (could of had some experience in using this method) but the expanding foam is a cracker!  Wait till it stops, bung a couple of cans in it n bugger off quick.

[Kiwifruit]

Think l must have eaten some of that expanding foam thinking it was cream in a can over xmas 

[KiwiCol]

Same here!, mine was disguised as beer & food - cunning.

I can't hear my aircon unit as the doors and windows are normaly closed to keep the house nice and cool.

And that's where the problem starts Tony, the neighbour doesn't have a pump and his windows are open.
I installed a 3 phase 10KW unit in my place with two fans about 600mm each across, but I bought a unit with fans on top so it wouldn't blow the fence over.
I never even told the owner next door when I installed it.

Would the intake accept prawn shells, fish oil spray, DPF cleaner spray, its horrible.

I'm all for going to council. In fact my email is all done. What's holding me back is it might be classed as a dispute. The missus is not so keen. The bloke is an utter arsehole. My friend 'Karma' has now dealt him a very bad hand health wise. Very bad indeed. So much so he is restricted to drinking a litre of fluid a day. For the rest of his horrible life.  I have built a pyramid of empty Fosters cans on the windowsill in my conservatory. In his full view. Mrs Brush says I'm cruel. Karma is a wonderful thing...

We are getting some fencing contractors down tomorrow. We have a six foot fence with Yorkshire boarding. With 1 inch gaps. I'm looking at refencing with no gaps.

I invested in a leaf blower autumn. I had to google it to find the loudest... At 0901. I'm out most mornings.

I reckon the thing was installed by some cowboys. Unless he was told of the sound implications. And said bugger it? Oddly enough. In Scotland these things are not allowed within 100m of a neighbouring property. Says it all really.

And thanks yeah. I've become an expert on Db frequency. A jump from 42 to 54 is considerable. Especially when we live in a small village. With no ambient noise whatsoever. We were out the other night. It's audible six properties away...!

Don't worry. I'm on with it. I wish they did draw air in. I'd did look at the weather forecast for an easterly wind. To crank my log burner up (for all you lads in Australia you'd better google it) just to stink him out!!

[Kiwifruit]

Karma can be the best response. Its just the waiting for it that pisses me off.
