How do I reduce the noise of a power portable generator?

Question

I have a portable 5.5kva power generator and i would like to know how its noise can be reduced. can i use mufflers to dampen the sound just like a car? will it put more load on the generator?

Answer 1

DoNot put a muffler on it.
You are correct it will put more of a load on the Gen-
The best thing to do is see if there is a different muffler from the Man- to make it more quiet.
Also There is 1 thing you can do.
If you can get a new muffler to extend from the one on the gen you can do this but only if the new muffler has No Restriction 100 free flow.
Also you do not want to build a box around it either. You can do this only if there are vents to let the new air in and bad air out. This will bring down the sound a bit. But be carefull Most units are air cooled and you dont want to restrict it.

Answer 2

I had a similar concern and built a "three sided" box several feet wider/taller than the generator and lined the box with two inch thick foam insulating panels. The difference is very noticeable and the generator doesn't seem to be running any hotter at all. I cut two vents in the top just to be safe. I Haven't talked to my neighbors (kinda hate to ask them) but I imagine they're hearing more noise since the open side is to them.

Answer 3

The engine manufacturer may offer a quieter muffler or you can ger a steel flex pipe attach it to the muffler and stick the other end in a drum of water

Answer 4

Build a box out of ply wood to go over it

Answer 5

no...anything you do to lessen the noise will diminish the power. DON'T put a box over it....that's just plain stupid.

Answer 6

Shut it down.

Answer 7

Turn it off...
