Hmmm.

399 Euros for a bucket lined with cement and foam is a bit much, but I bet it does its job.

I've been toying with a concept a bit like that for trombone except its a cube to allow clearance for the slide.

It is an interesting notion… I like the idea of similar volume reduction as playing muted without the change in front end weight, blow, intonation, etc. I may something like this a shot the next time I feel the urge to tackle a DIY project.

• If I were to imagine a "window" that I could put my bell through and have room for my arm to work the slide it might be about 2 feet on the diagonal

• The distance from the bell to the end of the slide in seventh position is less than 4 feet.

With that in mind, and maybe some extra width at the far end to accommodate expressive slide-waving, one might construct a box like this...

It would be made of plywood with a layer of sheet rock inside and some shag carpet on top of that for sound dampening.

Some flexible material might drape around the opening to diminish escaping sound.

The sides could be fashioned to be held together with bolts and wing nuts or maybe some rails so that the thing could be broken down and stacked at the side of the room when not in use.

As it is very close to my practice mute (which is likely the world's best, just sayin'), I'm sure it's quite good. Though you can't pack it in your overhead bag very easily.

As long as the trumpet is placed in the cement before it sets.

I fired a deer rifle through a length of concrete sewer tube once. Well, more than once, half a magazine or so, enough to be sure it was sighted in.

It was a safety requirement at that range, forcing the rounds to go down range into a berm, and also supposed to reduce noise around the area. I don't know if it did that but it certainly reflected noise back at the shooter.

Something like this would easily work for trombone if it were on a boom stand instead of a tripod. Even in the trumpet version I would be inclined to have a separate music stand because not everyone likes to play under the stand like that.
