The purpose of the phone booths is to provide employees of companies a place where they can make private phone calls. The space that thanks to a special, low-noise design will give intimacy to the callers and peace and quiet to other people in their surroundings. The shape of Booths and the sound insulation materials of the highest quality used in them provide the adequate dispersion of sound. Double walls with acoustic panels in between significantly limit the transmission of the sound to the outside.
