The difference and practical application of soundproof room and anechoic room

In the production industry, soundproof room and anechoic room are often used. Some people are confused about the difference between the two products. Today, Jinghuan Environmental Protection will explain the difference between the two.

From the literal definition, the soundproof room and the anechoic room are soundproof, isolating the sound from coming in or out; the anechoic room has a soundproofing effect, which reduces the sound. However, in the actual application process, the two are actually the same, and are used to soundproof and reduce noise for equipment or to test products. Strictly speaking, the difference between a soundproof room and an anechoic room should be distinguished from its use function, not from its name.

The soundproof room is what we often call a soundproof room. According to its purpose and use function, it is mainly classified into industrial and residential types. Residential houses generally need to be soundproofed and decorated due to poor sound insulation in the room. Today we mainly talk about the application distinction of soundproof rooms in industry. In industrial applications, the soundproof room is also called the anechoic room, which is divided into two categories: equipment noise reduction soundproof room and test soundproof room.

Equipment noise reduction soundproof room is also called anechoic room, soundproof cover, industrial soundproof cover. Its principle is to soundproof the sound source separately, and use the form of soundproof cover to enclose the noise source in a relatively small space to reduce the spread of the noise source to the surrounding. The most common are punching machines, generator sets, crushers, central air conditioning units, air compressors, water pumps and other equipment that generate high noise.

Test soundproof room is also called silent room, noise laboratory, soundproof room, and more precisely called anechoic room, soundless room, and soundless room. It is mainly used to test the noise value of various electronic products, auto parts, household appliances, air conditioners, motors, fans, etc. The principle of this type of soundproof room is to create a quiet environment in a noisy environment, that is, a special acoustic test room. In the actual construction process, it is mainly designed and produced based on the actual noise value of the established environment and the background noise value that the soundproof room needs to achieve.

The above is the difference between anechoic chambers and soundproof chambers. Strictly speaking, they are divided into two categories: equipment noise reduction and acoustic testing.
