Only way you're going to get rid of it is probably by investing in a new shop cleaner. You can cut it down a bit by getting one of the Rigid shop mufflers but hardly the worth it.

There are always the ear protectors you can wear........but look here first......

Howdy,

Are you wearing good hearing protection?

WHAT????

How big is your shop vac? Is it a true Shop-Vac brand or another?

Is it a shrill whistle in a frequency range that hurts you hair? I have found one of two causes:

1) a small piece of thin wood lodged in the hose that must vibrate or otherwise cause the sound.

2) a small hole or gap between the hose and the end fitting.

Wiggle your hose around to see if you can dislodge something. You might also try pusing a smaller hose, like a garden hose through the vacuum hose.

Last time I "pused" a small hose, I was in a hospital bed after surgery.

I have one of the Ridgid mufflers, and it helps a little. I always wear hearing protection. I've found that strapping a piece of open cell foam over the top of the motor quiets the whine a little, and keeps the exhaust fan from blowing more dust into my face. It's thin enough and porous enough that it doesn't overheat the motor, even when run for extended time periods. I've heard of some people building a box for their shopvac out of thin plywood or hardboard, or even pegboard for more ventilation. Supposedly this helps a lot with noise. I'd guess that enclosing the shopvac in a cardboard box would help, if it was exactly the right size and the wheels could stick through the bottom. Probably wouldn't last very long, though. Good luck, Andy

Howdy,

You and I are on the same channel...

He also suggested that the OP "Wiggle your hose around to see if you can dislodge something."

All the best,

Wow!!

I'm impressed with all the great resp>The whistle. Is it there without the hose attached? While make dust

Howdy,

I was one of those commenting on the hearing protection.

It is now clear that you need two pair of such...

Absolutly hands down best method of removing loud shop vac and all other high pitch and most low pitch noises is to contract Rubella as a child and slowly loose you hearing over the decades so that by the time you have an interest in woodworking, all the racket everyone else complains about is not noticable. Every cloud :)
