Description: This book deals with the achievements of a new, rapidly developing branch of science. Discovered very early in the twentieth century, inaudible sound immediately drew the attention of research workers in various branches of science and engineering. Several thousand scientific papers have already been published on the properties of inaudible sounds and their practical application. Supersonic vibrations were first used for practical purposes in France. Especially noteworthy in this connection are the works of Academician Langevin. Soviet scientists have also played a prominent part in developing the science of inaudible sounds and the methods of their practical application. In this book we shall tell of various discoveries in the field of inaudible sounds. Some of the applications of inaudible sounds may not justify our expectations in the future; it is quite possible that we shall make mistakes in our explanations of the action of supersound, and shall have to begin our work anew. The study of inaudible sounds in 1956 was an unlimited field of activity for investigators of nature, and it opened up immense opportunities for the application of the creative power of man.
