Soundproof booth
A noise protection cabin is a possible measure to reduce airborne and structure-borne noise emissions . The cabin either protects the environment from the noise of a machine or system or the cabin is used to isolate from the ambient noise z. B. measuring rooms in the hearing acoustics or studio booths for sound recordings.
Industrial soundproof booth
The soundproof booth completely or partially surrounds the entire machine or the sound-emitting components with soundproofing elements. These are designed in such a way that they absorb part of the airborne sound. Soundproof booths are used in particular when measures to prevent the generation of noise cannot be taken at the point of origin.
Very different materials are used depending on the frequency characteristics of the sound, the required sound level reduction and the operating conditions. The outer shell of the cabin is the load-bearing structure and, on machines, is often made of sheet steel, aluminum sheet or plastic. The sound insulation is done by special foams or mineral wool, which are adapted to the frequency characteristics of the noise. On the inside of the cabin, the soundproofing layer is often openly accessible when there is little mechanical stress and no protection against liquids is required in the case of foams. In the event of higher mechanical loads, the insulation layer can be protected with a perforated sheet.
In the case of dominant noises in the lower frequency band and the impact of water, cooling lubricants and other liquids as well as heavy dust exposure, expensive double-shell noise protection cabins may be required. Openings in noise protection booths reduce the insulation effect achieved; the use of silencers may be necessary here.
Measurement and recording rooms
There are several providers of noise protection cabins in Germany for the different areas of operation. Soundproof cabins are particularly required in the field of hearing acoustics and studio applications.
The soundproof cabin is used in hearing aid acoustics as a sound-insulating (but not anechoic) room for hearing measurements and device adjustments. So-called room-in-room systems can be integrated into existing rooms without structural changes.
application
The noise protection booth can be used wherever optimized room acoustics with protection against air, body and background noise according to clearly defined noise protection values are required:
- as a diagnostic and measuring room in medicine and science,
- as a measuring and test room in industry, research and development,
- as a recording studio and practice room for musicians and speakers as well as for multimedia productions,
- as a meeting and interpreting booth at meetings, trade fairs and conferences or
- as an oasis of calm and relaxation or a work space at home.
Layout and function
The soundproof booth stands free in the surrounding room and does not touch walls or ceilings ("floating" room-in-room system). The own floor, consisting of several sound-insulating layers, minimizes the transmission of structure-borne noise.
The installation of a room-in-room system has low requirements: The minimum size for the installation space should be nine square meters with a minimum ceiling height of 2.4 meters of the surrounding space. It is usually not necessary to intervene in the surrounding building structure; the soundproof cabin fits into any environment.
Equipment extras such as permanent, noise-free ventilation and air conditioning, daylight guidance through highly insulated windows, LED lighting and suitable furniture create a pleasant room climate and working environment.
Soundproofing
The soundproof booth is not a sound-free, but a sound-insulated room. This means that a fixed amount of noise and structure-borne noise cannot get into or out of the room. The specific construction, type of construction and the materials used define the level of sound insulation.
