COUST box

Phone booth with maximum absorption

The COUST box is an open phone booth where one can make calls without disturbing colleagues. It is constructed with a sturdy aluminum frame, features a stylishly finished work surface, and is mounted on the wall.

The unique filling of this phone booth ensures maximum sound absorption. The acoustic material is of very high quality and optimally structured. Each side of our phone booths is fitted with an MDF sound stopper on the back, which reflects sound. This way, the sound is absorbed not once, but twice!

The efficiency of the COUST box is remarkable: it reduces sound by 15 dB. This means that the sound source (in this case, the speaker) seems five times farther away. With this, the COUST box firmly holds a leading position among open phone booths.
