V.V.Meleshko Generation of acoustic waves in half-space by a rectangular source of finite dimensions |
Acoustic bulletin, Vol. 2 ¹ 1, (1999) |
| The analytical solutions for two-dimensional problems on sound radiation by a rectangular piezoceramic transducer into acoustic half-space baffled with soft or rigid screen have been obtained. The far-field pressure directivity patterns have been constructed; they are in a good agreement with experimental data. The efficiency of sound radiation for several normal modes of planar vibration of the rectangular transducer has been estimated. |
