Abstract
Acoustic radiation control method and system are provided. The acoustic radiation control method includes: configuring a speaker array; obtaining transfer functions of speakers in the speaker array based on configuration of the speaker array and directivity of the speakers; obtaining, based on the transfer functions of the speakers, source strength of the speakers which enables acoustic radiation of the speaker array in a first zone greater than acoustic radiation of the speaker array in a second zone; and applying the source strength of the speakers to the speaker array. By the method, acoustic radiation may be controlled more accurately, a sidelobe level may be constrained more effectively, and the number of speakers in the speaker array may be reduced.
