Sound-absorbing box for playing the trumpet



To muffle sound when playing musical instruments fixturescalled mutes. This name has the same root as the word "sign language". The mute for the pipe creates back pressure, which is somewhat inconvenient. An alternative would be a small plywood booth, the walls, the floor and ceiling of which are covered with sound-absorbing material. But the author of Instrictables, under the nickname nomuse, came up with a less cumbersome desktop sound-absorbing box that, although more than mourning, is smaller than such a booth. How to use it is shown on the KDPV. And inside there is enough space for a microphone to record how you play the trumpet.

The master begins with the manufacture of a model of foam insulation. Details of the layout are interconnected with fabric adhesive tape. It turned out like this:

The box dimensions should be selected individually depending on the height of the table, and the diameter of the hole - depending on the diameter of the pipe. If a musician plans to receive a pulsating sound using a device resembling a plunger, available in musical instrument stores, the diameter will have to be slightly increased.

Having decided on the size, the master cuts out the details from half-inch plywood made of Baltic birch. Before assembly, he glues the parts from the side facing inward with sound absorbing material. The master chose Bonded Logic's UltraTouch, for soundproofing properties it is no worse than glass wool, but safe. Cutting the details from the sound absorber into the size taking into account the thickness of the adjacent walls, the master glues them with glue-spray 77 from 3M. And the sound absorber and glue can be replaced with similar ones, the main thing is not to use anything containing glass wool. The pasting process looks like this:



Finally, the master glues the box (ordinary PVA glue is suitable here), clamps it with clamps and leaves it until the glue hardens completely:



Thereafter homemade ready to go. And the phrase “play in the box” takes on a new, completely different meaning.
