Controlled interference from a dual layer loudspeaker
Controlled interference from a dual layer loudspeaker
Controlled sound interference using a prototype dual-layer loudspeaker array comprised of 16 loudspeakers has been extensively investigated. Performance in terms of directivity and sound quality are examined. Results determined by the practically implemented conventional control methods show the inevitable trade-off between the quality and directivity. As an alternative method, weighted minimization of mean square error with a "low priority zone", controls the source strengths in order to obtain better sound quality in the bright zone as well as a lower sound level in the dark zone. A wider bright zone with better sound quality and a quieter sound level in the dark zone has thus been realized. The results of simulations and experiments are shown to be in excellent agreement.

Abstract
Controlled sound interference using a prototype dual-layer loudspeaker array comprised of 16 loudspeakers has been extensively investigated. Performance in terms of directivity and sound quality are examined. Results determined by the practically implemented conventional control methods show the inevitable trade-off between the quality and directivity. As an alternative method, weighted minimization of mean square error with a "low priority zone", controls the source strengths in order to obtain better sound quality in the bright zone as well as a lower sound level in the dark zone. A wider bright zone with better sound quality and a quieter sound level in the dark zone has thus been realized. The results of simulations and experiments are shown to be in excellent agreement.
