Abstract:
1. A system comprising: a sound generator that generates first and second electronic frequency modulated noise signals; first and second loudspeakers respectively receiving the first and second electronic frequency modulated noise signals and concurrently transducing the first and second electronic frequency modulated noise signals to audible signals in a room environment containing the first and second loudspeakers; a binaural detector that transduces the audible signals to detected signals; one or more filters that filter the detected signals from the binaural detector to obtain sub-band signals for at least two sub-bands of the detected signals; a signal processor coupled with the one or more filters that determines binaural activity of the at least two sub-bands of the detected signals; and an analyzer coupled with the signal processor that determines objective listener envelopment of the loudspeakers-room environment based on the binaural activity of the at least two sub-bands of the detected signal.
