Abstract

The sound radiated from an electrically excited laminated piezoelec- tric plate is computed. Voltage distributions obtainable from an array of finite sizeelectrodes are used to examine the limitations of actively suppressing sound radi- ation at particular spatial wave numbers. The problem of active cancellation ofsound reflection at oblique incidence is investigated.
