sound proofing

[james c]

I have a 4 stroke generator at my bug out place,can anybody tell me how to sound proof it,taking into account ease of access to refill it,any help please

used a small shipping container and bury it failing that fill sand bags with soil and stack them around it , the soil will absorb the sound

Hi

Take a look at the big generator sets from FG Wilson or someone like that. You will see they are in a steel box that is lined with acoustic foam.

But importantly they have the induction air piped directly from the cool ambient air, and the exhaust piped directly out f the box and away from the induction pick up point and cooling air access.

Remember to ensure there is enough airflow for the engine and generator to cool sufficiently. In order to reduce noise at the air inlet and outlet position, these manufacturers use over lapping louvres, again, with foam glued onto them.

Might help you design a mini version. But remember the air inlet & exhaust flow, and cooling air flow are critical to long term reliability.

Cheers

Good for you James!

Carrying on with the soundproofing theme ... anyone have any knowledge of how to soundproof a central heating pump, or how safe it is to do so? Old one had broken down (and was pretty noisy when it did work) this one is still bad, last night I could hear it on a different floor, and in a different room on the floorplan (i.e. not underneath it, if you know what I mean).

A pump will be noisy if not fitted correctly ie in the proper position. It can be noisey if there is air in the sytem or rubbish ie old solder, flux shavings etc. Its not easy to sound proof as they get very hot and have electrical connections, also easy of access. On most pumps ie "grundfoss" you can bleed the air.

Get one of the wilo pumps much quieter than the grungfos ones , you could go for the ones with the extra insulation , pre fab to suit, make sure that there is plenty of support in the pipe work and that nothing is resting against the pipe work , that can amplify the sound as well , air in the pipes can make it worse too

Thanks both, I've made a note of those points.
