摘要：

The problem of sound radiation by a grating formed by free-flooding cylindrical piezo-ceramic shells excited by a harmonic electrical signal is solved. Extended quantitative data on the near and far fields is given. The analysis of energetic efficiency, directivity and frequency band features of the grating is conducted on the basis of these data. A variety of acoustical properties of the grating are determined, which can be significant for practice.
