  • Patent number: 8564339
    Abstract: A method and a system for measuring amplitude and phase difference between two sinusoidal signals, using an adaptive filter. The method generally comprises measuring a sample of an output signal of a system excited by a sample of a reference signal; using an adaptive filter and the sample of the reference signal to determine a and b coefficients that minimize a prediction error on the sample of the output signal, iteratively, and determining the amplitude and/or phase of the output of the system using the a and b coefficients.

  • Patent number: 8116461
    Abstract: A control method to automatically adjust the volume of a sound transmitter based on the measurement and the computation of the acoustic statistics of the room where the sound is emitted. The system comprises at least one sensor, a calculator determining statistics of the signal collected by the at least one sensor and a controller using these statistics provided by the calculator to adjust the volume of the transmitter in the room.

  • Patent number: 7460675
    Abstract: A system and method for generating a masking noise level and spectrum automatically adjusted to obtain a target masking noise spectrum in a room. The system comprises a white noise generator and a mask filter automatically determined according to a correction of an acoustical response of the room and to the target masking noise corrected by an ambient noise.
