How To Make A Generator More Quiet. Make sure to install your generator away from your home or location. Also, if you place the generator near walls or even the side of an rv the sound can bounce off of those things and be amplified as well.
Connect one end of a section of hosepipe to your generator’s exhaust and place the other end in a bucket of water. The water dampens the noise from the generator making it very quiet. And to make it worse, the exhaust might be channeled toward the house directly.
Build an enclosure to the generator;
With the decibel scale ranging from 0 db (total silence) to 140 db (a gunshot noise). More open spaces make for quieter sounding generators. On the market, the quietest decibel rating of a silent generator is currently at 50 decibels, which is equivalent. Using a generator silencer or muffler, installing rubber feet, grounding on a soft surface, keeping the generator away, setting the exhaust pipe vertical and using a sound deflector are some of the most effective ways to quiet a generator.
