Abstract
Provided is a method of adjusting a distribution of spatial sound energy, including storing information associated with a sound transfer function from each of speakers of a speaker array to a position of at least one listener, and information associated with the sound transfer function from each of the speakers of the speaker array to a far-field position, and generating at least two sound beams maximizing a far-field sound pressure attenuation with respect to a source signal, based on information associated with the sound transfer function, in order to form a personal sound zone in the position of the at least one listener.
Claims24
An operating method of an audio apparatus including at least one processor and a speaker array to form a personal sound zone in a position of at least one listener of the audio apparatus, the method comprising:
- generating, via the at least one processor, at least two sound beams maximizing a far-field sound pressure attenuation with respect to a source signal, based on information associated with a sound transfer function;
- generating, via the at least one processor, a multichannel signal by performing convolution of the at least two sound beams;
- and
- outputting, via the speaker array, the multichannel signal.
An apparatus for adjusting a distribution of spatial sound energy to form a personal sound zone, the apparatus comprising:
- a beam generator to generate at least two sound beams maximizing a far-field sound pressure attenuation with respect to a source signal, in order to form a personal sound zone in the position of at least one listener;
- a convolution calculator to generate a multichannel signal by performing convolution of the at least two sound beams using at least one processor;
- and
- a speaker array unit to output the multichannel signal via a speaker array.
