聲級計是通常的嘈音污染預估方法檢測設備，聲壓級預估方法是其通常的技能。談談更多技能單調的聲級計，更多人也日常習慣稱其為“音貝儀”或“嘈音計”等。它是一種種自動化技術檢測設備，但又各種于電壓值表等主觀性自動化技術義表。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.在把聲手機信號切更換為電手機信號時，需要摸擬人耳對超聲波表現運行速度的時特征參數；對高底頻有不一樣流暢度的幀率特征參數還有不一樣響度時變更幀率特征參數的比強度特征參數。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.輕便式測振儀適宜于物理裝置的震動幅度側量，特備是旋轉和導桿物理中的震動幅度側量。可側量震動幅度位移、網絡訪問速度和加網絡訪問速度三性能。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.利用該測試儀器在滾針軸承座上自動測量的統計數據，比國際聯盟規則ISO2372，還中小企業機器人客觀存在的規則就可認定機器所屬的感覺。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.
