聲級(jí)計(jì)和振動(dòng)儀的區(qū)別

聲級(jí)計(jì)是基本的噪聲測(cè)量?jī)x器，聲壓級(jí)測(cè)量是其基本的功能。對(duì)于很多功能單一的聲級(jí)計(jì)，很多人也習(xí)慣稱其為“分貝儀"或“噪音計(jì)"等。它是一種電子儀器，但又不同于電壓表等客觀電子儀表。

Sound level meter is a basic noise measuring instrument, and sound pressure level measurement is its basic function. For many sound level meters with single function, many people are used to calling them "decibel meter" or "noise meter". It is an electronic instrument, but it is different from objective electronic instruments such as voltmeter.

在把聲信號(hào)轉(zhuǎn)換成電信號(hào)時(shí)，可以模擬人耳對(duì)聲波反應(yīng)速度的時(shí)間特性；對(duì)高低頻有不同靈敏度的頻率特性以及不同響度時(shí)改變頻率特性的強(qiáng)度特性。

When the acoustic signal is converted into electrical signal, the time characteristic of human ear's response speed to acoustic wave can be simulated; Frequency characteristics with different sensitivity to high and low frequencies and intensity characteristics changing frequency characteristics at different loudness.

便攜式測(cè)振儀適用于機(jī)械設(shè)備的振動(dòng)測(cè)量，特別是旋轉(zhuǎn)和往復(fù)機(jī)械中的振動(dòng)測(cè)量?？蓽y(cè)量振動(dòng)位移、速度和加速度三參數(shù)。

Portable vibration meter is suitable for vibration measurement of mechanical equipment, especially in rotating and reciprocating machinery. It can measure three parameters of vibration displacement, velocity and acceleration.

利用該儀器在軸承座上測(cè)量的數(shù)據(jù)，對(duì)照國(guó)際標(biāo)準(zhǔn)ISO2372，或者企業(yè)機(jī)器本身的標(biāo)準(zhǔn)就可確定設(shè)備所處的狀態(tài)。

Using the data measured by the instrument on the bearing pedestal, the state of the equipment can be determined according to the international standard ISO2372 or the standard of the enterprise machine itself.
