### Sound prooving

- [Techniques for industrial machines & material supplier - UK](https://www.customaudiodirect.co.uk/soundproofing-industrial-machines#:~:text=Materials%20such%20as%20our%20Pyrosorb,reduce%20the%20overall%20sound%20output.)

|
||
|
||
Since proper material seems expensive (200E for 2sqm), 2 optional layers are offered. The first should remove about 30dB, the second 60.
|
||
|
||
|
||
|
||
An additional hopper and as well an exit chute is required in this case.
