Guide to Exhaust Silencers & Noise Reduction

The number of discs can be varied to fine tune the flow and noise reduction. The full number of discs will equal or exceed the surface area of the pipe exit and will give the most flow but the least noise reduction. Removing the discs will reduce the exit surface area so give less flow but more noise reduction.

Generator Quiet Box and Other Ways to Reduce Generator Noise

Rubber absorption – Medium noise reduction. If your generator is sitting on something hard – say concrete – it is going to make more noise as the engine runs and the unit shakes a bit. greatly reducing generator noise. Pointing the exhaust (and the noise) up into the sky works well to lessen noise when camping in an open space. The
