【正文】 rections in state of packing. 7. CONCEPT OF UNITThe difference between concept of unit “Pascal” and the one of unit “μbar” can be explained as follows. In calibrating the sensitivity of ECMs,The sensitivity is manifested differently according as the unit is “Pascal” or “μbar”. That is , the sensitivity will be increased by 20 dB in the usage of unit “Pascal”.Example:60dB(0dB=1V/μbar)=40dB(0dB=1V/Pa) STANDARD TESTING SENSITIVITY REQUEST : The tolerance of sensitivity is not over +/ 3dB to standard microphone. TESTING WAY : microphone with standard operating condition. Put the microphone and standard microphone to face the sound output place(speaker), the distance from sound output to microphone amp。 DIMENSIONSECM。5%PARAMETERSYMBOLCONDITIONLIMITSUNITMinCenterMaxSensitivitySf=1KHZ, =1Pa0dB=1V/Pa363330dBOutput impedanceZoutf=1KHZKΩCurrent ConsumptionIDssVS= RL=500μADirectivityOmnidirectionalSignal to Noise RatioS/NS:(f=1KHz,=1Pa)N:(AWeighted curve)
