Distance: 30cm, Sensitivity: 0dB=10V/Pa, Sound pressure level: 0dB=20µPa. Refer P19. The sensor can be used in the operating temperature range. Please refer to individual specifications for the temperature drift of Sensitivity/Sound pressure levels or environmental characteristics in that temperature range. Directivity and detectable range are typical values. They can be changed by application circuit and fixing method of the sensor.
