Abstract: The total sound power (TSP) produced by a loudspeaker can be severely affected when placed in typical living rooms. General approaches consider an equalization filter designed toward a desired target. The computation of the TSP requires measurements on a number of microphones spaced in the room. In this work, an automatic method to estimate the TSP without the use of numerous measurements is proposed. The proposed method includes a static microphone configured to measure the near-field sound pressure of the driver, and a controller to determine its velocity to automatically adjust the sound power levels to an acoustic environment. Results in typical living rooms show an average standard deviation error of 2.6 dB on the estimation of the TSP.
