Kinda depens on where yer at... If you out in the Booneys and you can do it with out messing up the site dig a pit at least low enough for the exhaust to fit below "grade" this will reduce a conciderable amount of noise. also modified exhaust systems that vent up-wards also help.

I suppose you could build some kind of collapsible "dog house" to put over it, like those fold up wire cages some people use for their dogs. Add a few slabs of foam insulation once it is erected and maybe that would help.

Whatever you try, be sure to leave adequate ventilation - those engines are air-cooled.

The EU2000 is something like 59dB which is about what normal conversation is. There is a point of diminishing returns. Complete silence is impossible. Even fuel cells make some noise.

The folding enclosure is a good idea. I like Owens Corning 703. Be sure to have a tube for the exhaust to get out, and maybe an outlet for the hot cooling air, too, depending on how tight the enclosure is. Most noise travels line of sight, so the enclosure can be sort of a noise barrier, not a real close tight enclosure.

Ant, the normal foam insulation does very litte for sound control. Now you can build a barrier that would say be V-shaped and maybe even a sloped roof over the generator, and leave a back wall open. In order to stop the sound you really need a sound absorbing material which tend to be heavy and dense. You can build something with a sound reflective material, i.e. a hard surface, that would just reflect the sound away from you toward a direction that you or anyone else would not mind.

Since sound is pretty much straight line transmisson, much like light, the barrier is the easiest solution, provided you do not reflect it to a neighbor.

To build a total enclosure, you will have to pipe out the exhaust and have sound traps or acoustical louvers to get air into and out of the enclosure, plus a fan to supply the generator with cool air and exhaust the warm air.

We build sound attentuated chiller packages and the sound attentuation material and techniques can get expensive. Anytime you have moving air, it also creates it's own sound and this has to be dealt with. So the cooling fan on the generator is a sound source as is the mechanical noise from the engine and generator.

On an air cooled package, we have inlet sound attenuators in the form of louvers with sound absorbant materials. We often put sound traps on the air outlet from the unit. We also provide acoustical wraps on some components within the unit. When we line an enclosure with sound absorbing material, it is a dense foam specifically for sound absorption. The normal thermal insulaiton will do little for sound absorption.

Ken, I am interested in the foam you mention. Got any specs, sources and prices? The Owens Corning 703 has served me well in audio and RVs, but I am always looking to tweak.

The Owens Corning 703 in 2 inch thickness (unfaced) has a NRC of 1.0, and is .70 in 1 inch thickness. 3 inch thickness is only 1.1, so I haven't used it. I forget the price, but it is not a lot.

.....the absolute best sound deadening is lead sheeting/lead foil......used to use a demo with a battery door buzzer running constantly and a lead box....droped in the buzzer and put on the top.....guess what?....no noise!......now the only questions is where do you get thet lead foil these days.....?.....geof kaye

Enclosing any portable generator is a bad idea. I am aware that some have done it. I am also aware of at least one that melted his generator. If the warranty people find out, your warranty is history. Take a look at the instruction manual. Buried in the warnings it will say something about "free air" and how the generator is designed to be in open air. Why would anyone want to make an EU2000 quieter anyway? With two running, I can sit within 10' and hold a normal conversation.

Anything lightweight will be worthless. The pit idea works. A series of cinder blocks stacked up without mortar to make a one or two sided reflector will work too. Just make sure not to aim the sound at the neighbors. Sound is pretty easy to reflect, but pretty difficult to absorb.

That generator is quiet enough in most cases a good heavy duty extension cord would be my choice.

I try to run any electronics off an invertor and if I have to charge the batteries I do it when we are away in the day.
