  • Acoustic impedance sensor designed to measure the input acoustic impedance of a waveguide
    Patent number: 8544327
    Abstract: The present invention concerns an acoustic impedance sensor designed to measure the input acoustic impedance of a waveguide. This sensor is characterized in that the source is a piezoelectric pellet that makes it possible for the determination of the acoustic impedance of a passive acoustic element to remain coherent for low frequencies while preserving an inexpensive implementation of the sensor.
