Abstract
Audio electrical signals are controlled to be provided to a plurality of electroacoustical transducers of an array to achieve directivity and acoustic volume characteristics that are varied with respect to a parameter associated with operation of the array. The controlling of the signals results in a change in the radiated acoustic power spectrum of the array as the characteristics are varied. The change in the radiated acoustic power spectrum of the array is compensated.
