Need to quiet portable generator with additional muffler?

Enclosures present a different set of challenges. The biggest one is heat. If this enclosure traps heat, you are left to find a way to dispense with it.

Yep. That's why I opted to use the barn as an enclosure.

I would estimate it reduces the noise by 1/2. I have had to go in there in the middle of the night to turn it off. You certainly become wide awake, when you walk in the door and hear it running. :shocked:

A muffler only helps if you are using a budget unit with a cheap muffler to start with. If it is a better unit with a good sized low tone muffler, it's not going to get a lot better than that.

A couple of sheets of plywood connected with a door hinge and set at 90 degrees wil isolate the sound quite abit.

More like redirect the sound. A good option is toward the neighbor, with the Harley. :thumbsup:

LOL so true. My neighbor's grown daughter lives moved home and has this gawd awful muffler system on her car, sometimes I can hear from 2000 ft, but ALWAYS from 500 ft when she leaves or comes home around 11pm. When i mentioned it, he stated it came with the car so must be legal. I oriented my diesel gen exhaust that direction, except I don't run it between 9pm-7am.

I have a "dog house" that my generator sits inside of. The back is solid wood, the sides are large (as in about 30x30) louvered screens, and the front is a steel door. There's a small roof over the top and the wiring runs directly underground to the disconnect panel in the basement.

Makes a HUGE difference in the sound level and there is no issue with heat or ventilation.

Like the guys have said, most of the noise is mechanical if the stock muffler's any good at all. I have an EZ5000 Honda generator I tried to quiet down with a car muffler. Most of the noise was mechanical, although it quieted the exhaust note to the same as a car idling in the driveway.

I am fabricating an extension to attach to the stock muffler.

I am going to run the generator inside the detached garage/workshop and run the exhaust extension out the side entry door.

I'll let ya know how it works.

My buddy also gave me an old motorcycle muffler I may play around with also.
