Intensity Microphones

  1. 40GK 1/2" Intensity Mic Kit
    Freq response: IEC 60651 Type 0 IEC
    Dyn range: 27 dB(A) to 163 dB
    Sensitivity: 12.5 mV/Pa

    G.R.A.S. 40GK 1/2" Prepolarized Intensity Microphone Kit

    The 40GK is an IEC 61094-compliant, WS2F ½" prepolarized sound-intensity microphone set. The microphones in the set are two 40GI microphones - two phase-matched free-field condenser microphones with extremely well-controlled phase characteristics for use in sound-intensity probes. This microphone pair has a free-field frequency response that complies with IEC 61043 1993 Class 1 and IEC 60651 Type 1 in the range from 20 Hz to 10 kHz. Learn More
  2. 40AI 1/2" Intensity Mic Pair
    Freq response: IEC 60651 Type 0 IEC
    Dyn range: 20 dB(A) to 157 dB
    Sensitivity: 25 mV/Pa

    G.R.A.S. 40AI 1/2" Ext. Polarized Intensity Microphone Pair

    The 40AI is an IEC 61094-compliant, WS2F ½" externally polarized sound-intensity microphone pair especially suited for sound-intensity and sound-power measurements, sound-source location and IEC 61043 Standard Instrumentation. Its equivalent prepolarized version is G.R.A.S. 40GI
