Genny soundproofing

I was thinking of insulting the cabinet that the genny is in to cut down the noise for neighbors. i could sleep through a bombing so it doesn't bother me. I was wondering what would be the best to use, fiberglass insulation, foam board or whatever.

This is a good question. I believe the majority of the noise is directed downwards and I have noticed that the amount of noise also depends on the surface I'm parked on. Concrete and asphalt would obviously reflect the noise and not dampen the sound at all. A rough dirt/pine needle/bark/grass covered surface absorbs or deflects much less noise.

I had considered placing a homasote (sp?) board under the generator, but it would fall apart too easily and be too bulky to carry. Another idea is to get the foam garage mats that link together and place them under the genny. Though I don't know if the downdraft from the cooling fan would blow it away.

While it is a little noisy inside the coach, mainly from transmitted vibrations, I think most of the outside noise comes from under the compartment the genny is housed in.

I'll be interested in hearing other's observations and solutions. Thanks for bringing the topic up.

Tom

A old peice of carpet on the ground/pavement helps quite a bit. Go to a carpet store dumpster on Saturday morning and it's free. When done return.

""I was thinking of insulating the cabinet that the genny is in" Check with the manufacturer to see if you can insulate the cab. it could possibly
overheat the genset, don't block any cooling grates, I'm not sure if that would help much or not once you did that for outside noise, maybe running a tailpipe out the back if not already would direct the sound to a different area?

There are a number of self adhesive sound proofing materials that could be used for the cabinet itself. Underneath, there are some suggestions already on the thread that sound very inexpensive and worth a try.

I used automotive Low-E and 3M adhesive and followed the clearances specified by the Onan installation manual. The exhaust can be quieted with the Onan resonator and/or SuperTrapp.

Genturi for exhaust and carpet under too.

A roll or other shape to dissipate whatever is there.

Something placed in front of with air space may help too.

Tinker with it.

I thought about doing this a few times, However, I just don't feel comfortable blocking any portion of open air area that would hinder the cooling of the unit....JMO

It's on my to-do list. I've researched some sound proofing materials, here's a few:

HushMat sound deadening & insulation material reduces noise and heat in Boats, RV's and Recreation vehicles

25^ Mega Mat Sound Deadener Noise Killer | FatMat Sound Controlâ„¢

GT MAT SOUND CONTROL, LLC Automotive Sound Deadener Dampning Material Dynamat Alternative

Thermozite Insulator Padding - Sound & Heat Solution

Or a spray-on solution if you could access the inside of the gen set enclosure:
Sound Control Insulation - Sound Damping Coating | LizardSkin

RV Insulation Coating - Recreational Vehicle Thermal Insulation | LizardSkin

Onan specifies clearance and air flow requirements in their installation manuals. Go forth with knowledge.

Rather than just putting carpet on the ground suspend it under the gen but with enough room for airflow. This will give be better sound absorption than on the ground. Sound absorping foam sheets work even better but takes more room to store.

This Duct Mastic Sealant 1 Gallon Generic | eBay with 2 cans of spray Boom Mat. I found its the easiest way to reduce the sound by 25%-35%.
