Eco Tech - Model Type IFC-1 - Infrasound Calibrator
From Measuring Instruments- Infrasound Measurements
Infrasound calibrator Type IFC-1 is used to calibration of acoustic measuring instruments adapted to measurements in the infrasound frequency range. The Type IFC-1, when connected to the microphone of the tested instrument generates a sinusoidal sound pressure signal SPL = 94 dB at frequency 10 Hz or 20 Hz in its pressure chamber. Both frequencies enable to test G weighting network of sound level meter. The calibration method is in compliance with Annex A of ISO 7196.
