  • Type IFC-1 - Infrasound Calibrator Infrasound Calibrator Ttype IFC-1 is designed for calibration of acoustical instruments intended to meter of low-frequency signals according to ISO 7196 :1995 "Acoustics - Frequency weighting characteristic for infrasound measurements". Measuring microphone of the tested instrument is tightly coupled to the acoustic actuator of the infrasound calibrator by a pressure chamber. Internal acoustical actuator produces a low-frequency sound pressure in the cavity.
  • CAL150 - Microphone Calibrator The Larson Davis Model CAL150 is a precise microphone calibrator intended for the 3/8" diameter microphones typically used on the, SoundTrack Lxt class 2, Model 700, 710, 712, and 720 SLM/Dosimeters and the Model 705 Noise Badge. The CAL150 provides a choice of calibration sound pressure levels, 94.0 and 114.0 dB (switch selectable) at a frequency of 1 kHz.
