1.  The Invention
	Title INFRASOUND CALIBRATOR The problem the inventor(s) wanted to solve The Infrasound Calibrator is designed for the calibration of acoustical instruments intended to measure of low-frequency signals according to ISO 7196 :1995 Acoustics - Frequency weighting characteristic for infrasound measurements. Description. The measuring microphone of the tested instruments is tightly coupled to the acoustic actuator of the Infrasound Calibrator by a pressure chamber.The internal acoustical actuator produces a low-frequency sound pressure in the cavity. The Infrasound Calibrator produces sinusoidal reference signal of 1 Pa RMS sound pressure at 10 Hz. It can produce also the same sound pressure at 20 Hz for testing the reference level of infrasound G filter frequency response. Presentation. POSTER Fields of application (maximum 2 lines) The Infrasound Calibrator can be use anywhere where well definied sound pressure is required, and is especially suited for the calibration of measuring instruments in the field. Advantages (maximum 5 lines) Application of the Infrasound Calibrator for calibration of low-frequency measuring instruments guarantee the calibration results to be traceable to the national standards in the infrasound range.
