What are the anechoic chambers used for?
Anechoic room is to point to a room without reflection, on the wall of anechoic room are laid sound absorbing material with good performance, sound absorbing coefficient reaches 99% above.
In modern society, sound is everywhere in our life, and even noise is an indispensable part of human life. And the existence of sound is not a good without harm, sound enterprises in the test of professional sound products, usually in the professional anechoic room noise test. Anechoic room is to point to the room that does not have reflex, on the wall of anechoic room all laid has sound absorbing material with good performance, sound absorbing coefficient achieves 99% above. Accordingly, indoor won't have the reflection of sound wave.
Anechoic chamber is an important experimental place in acoustic experiment and noise test. Its role is to provide a free field or semi-free field space of low noise testing environment, and adopt good sound insulation and vibration isolation device, to avoid the interference of external environment. In the professional sound and lighting industry, it is a special place for
testing sound boxes, horn units and other sound equipment. General sound absorption material sound absorption performance is a function of frequency, the lower the frequency of sound absorption performance is worse, the high frequency of sound absorption material sound absorption performance is better. However, the wavelength of the high-frequency sound wave is short, and the support and network of the measured parts placed in the anechoic chamber scatter the sound wave more.
Anechoic room is used in noise control, sound insulation and vibration prevention engineering of civil buildings, air conditioning rooms, garages, pavilions, hotels, restaurants, shopping malls, supermarkets, hospitals, office buildings and other places. Sound design, construction and installation engineering of recording studio, studio, performing arts hall, concert hall, theater, cinema, piano room, teaching and research office, multi-function hall, gymnasium, conference room and other buildings. All kinds of sound insulation door, sound insulation window, sound insulation room, sound insulation cover, sound insulation screen and other sound insulation engineering. Laboratory, silencer room, silencer box, simultaneous interpretation room, hearing testing room and all kinds of electronic, electrical, medical, mechanical equipment, power engine, aircraft engine and other testing and other ultra-quiet no sound laboratory engineering.
