What resources to look at for building a quiet generator compartment?

You need to understand Jeanie his wife has health problems and Dick spends most of his time with her,I am the same I don't answer my phone for days then get around to calling people back

Justin won't even take a message for Dick because he knows it is unlikely he will call me back. That is fine if Dick is unavailable, but then he or his employees should just say he is unavailable.

The one and only reason I was looking to talk to Dick is several posters mentioned I should talk to Dick since I bought the generator from Wrico. I won't try to talk to Dick since I know he is unavailable now.

I might go with airbags. If I put them inside the box they only have to raise it 1/2" off the floor and I have plenty of room for that, and still have room for sound deadener above the box. Another good idea. Thanks for that. Might still use the pads for when the airbags leak down.

Pancake Electric fans! What a great idea rather than all the space taken up for the old school style design. And so cheap. A trip to a Pick and Pull and you'll find a lot full of electric radiator fans. Need bigger, same except for going to big truck wrecker for a fan that for sure will provide enough flow. Happy hunting

Here's my genset. Pics are pretty self explanatory I think...

I even bought the plywood from Dick "sound deadening" product. The photo I attached last time was not a finished install, this is.

Buy you a couple of sheets of lead lined ply wood and a cheap DB gauge from Amazon and go to work,I am sure the cage blower has 3 speeds same I used and I never had to use the high setting on mine and you could not hear the fan run. Build your box and use the DB gauge to find a problem area with a high noise level solve that which is not hard to do and you will be ok you are not building a rocket

What is on the other side of the radiator? Which way is air flowing through it? It seems the squirrel fan is pushing air in, maybe it's pulling air out?

The radiator is mounted in a box inside the compartment, the fan pressurizes compartment and forces air thru radiator, then thru the floor of the radiator box.

I don't think I am going to be using lead lined plywood unless I buy lead sheet and make my own. I found a place I thought was local, but it turns out only their corporate office is local. They manufacture and ship from Tennessee. $450 for a 4x8 sheet plus he said it would be several hundred for shipping. They are willing to sell me the product, but the salesperson said it could upwards of $1,000 with shipping and tax.

This will be plenty, smaller, both thickness and area, amounts for less. If I was really want to kill sound this would be a great start for DIY laminated sheets. Maybe 3/4" MDF, contact glue the lead sheet, then something less dense to absorb the mid-higher frequencies. Seal well and call it a day.

Our local Lowe's sells metal lined plaster wall board (Quiet Rock 530 RF +/- $200 per 4x8) which if sandwiched between 1/4" plywood would do the trick for blocking low frequency high energy noise. Egg crate foam rubber works good for high frequency low energy noise.

Actually, dense rubber floor mat works almost as well as lead for LF noise. Rubber mat made of chopped rubber re-glued together does not work well as there remains a reticulate of open passageways for sound to escape through. Jack

you just need to be willing to take a road trip to pick it up. done that many times.
