1. A method for using microphones and a signal measuring system to measure and optimize a sound system in a listening room, said method comprising the steps of:

  • (a) measuring the direct sound electro-acoustic response (“

    direct sound response”

    ) of a loudspeaker;

    (b) measuring the sound power electro-acoustic response (“

    sound power response”

    ) of a loudspeaker;

    (c) determining the average direct sound level;

    (d) determining the average sound power level;

    (e) determining a compensation value by calculating the difference between the average direct sound level and the average sound power level;

    (f) calculating a compensated direct sound response by subtracting the compensation value from the measured direct sound;

    (g) determining a weighted sound power response and weighted compensated direct sound response by weighting the sound power and the compensated direct sound response over a range of frequencies following a set of weighting values that represent auditory sensitivities to direct sound and sound power sounds;

    (h) combining the weighted sound power response and the weighted compensated direct sound response additively to calculate a weighted combined response; and

    (I) visually representing the weighted combined response.
