用于各類電子機械元件靜音測試等，房外80分貝，房內(nèi)20±1分貝，有防水、防火、穩(wěn)固等特點。

一類是由于機器體積較大，設(shè)備檢修頻繁又需進行手工操作，此時只能采用一個大的房間把機器圍護起來，并設(shè)置門、窗和通風管道。此類隔聲間類似一個大的隔聲罩，只是人能進入其間。另一類隔聲間則是在高噪聲環(huán)境中隔出一個安靜的環(huán)境，以供工人觀察控制機器運轉(zhuǎn)或是休息用，按實際需要也要設(shè)置門、窗和通風管道。

二、隔聲房是用于檢測設(shè)備的工作間，可為活動靜音房。靜音房采用四面及頂面吸聲，底層隔聲的方式使室內(nèi)達到低噪聲環(huán)境。其在隔音房內(nèi)本底噪聲值小于35-40dB(A)。隔音房除設(shè)置吸聲系統(tǒng)外，按實際還需要設(shè)置隔聲門、窗和通風系統(tǒng)、電氣系統(tǒng)等。

隔聲房按聲學(xué)性能分為

1.消聲/消音系列

2.靜音系列

3.隔音系列

4.屏蔽系列

For various types of electronic mechanical components silent testing, etc., 80 decibels outside the room, 20 ± 1 decibel in the room, waterproof, fire protection, stable and other characteristics.
One is that due to the large size of the machine and the frequent maintenance of the equipment, manual operations are required. At this time, only one large room can be used to surround the machine and doors, Windows and ventilation ducts are set up. This kind of sound insulation is similar to a large sound barrier, but people can enter it. The other type of sound insulation is to separate a quiet environment in a high noise environment for workers to observe and control the operation of the machine or rest. According to actual needs, doors, Windows and ventilation ducts must also be set up.
Second, the soundproof room is for the testing equipment of the work room, can be active silent room. The acoustic room adopts four-sided and top surface sound absorption, and the bottom sound isolation method enables the room to achieve a low noise environment. The background noise value in the soundproof room is less than 35-40 dB(A). In addition to the sound absorption system, soundproof rooms need to be equipped with sound insulation doors, Windows and ventilation systems, and electrical systems.
Sound insulation room is divided into acoustic properties
1. muffler / muffler series
2. Silent series
3. Sound insulation series
4. Shield series
