Book excerpt: Excerpt from A d104book of Sound: Being an Account of the Physics of Vibrations With Special Reference to Recent Theoretical and Technical Developments In addition to the large extension of frequency-range, new apparatus and new methods of investigation have been introduced which have completely transformed all branches of the subject. The very important analogy existing between electrical and mechanical vibrating systems is now in general use. Not only are electrical methods extensively applied in the production and reception of mechanical vibrations, but the theory of one is closely interlinked with that of the other. The familiar con ceptions of electrical potential, current, and impedance are now applied with almost equal facility to mechanical systems; we have mechanical filters analogous to electrical filters, and complex mechanical vibrating systems (e.g. Such as a gramophone sound box or a 'loud speaker') are now designed in strict accordance with electrical principles. Electrical methods are extensively used also as a means of amplifying mechanical vibrations, the feeble effects at a sound-receiving surface being converted into electrical currents, amplified electrically and reproduced as mechanical vibrations of greatly increased intensity. It seems desirable that these and the many other important developments should be recorded side by side with the earlier work of Rayleigh and his followers. I have endeavoured to write the book in a manner suited to the requirements of university students, but it is hoped that it may also prove of some value to those interested in the more technical, or applied, aspects of the subject. For those requiring further information a plentiful supply of references to original papers is provided. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
