The acoustic booth is an auxiliary automation element designed to isolate the peripheral communication device or to alert against extraneous sounds to ensure the quality of the device's use. Cabs are necessary for isolation from extraneous noise of industrial telephone sets, intercoms, light and sound alarms. The acoustic cabins are mounted on a wall, bracket or column. The cabins are made of plastic, stainless steel and isolate ambient noise to 25 dB. The design of acoustic hoods is adapted for the installation of Lelas devices.
