Scitus Academics Introduction To Acoustics by Gaohui Li, Eugen Mamontov
An acoustic wave basically is a mechanical oscillation of pressure that travels through a medium like solid, liquid, gas, or plasma in a periodic wave pattern transmitting energy from one point to another in the medium. The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source creates vibrations in the surrounding medium. This is well-known that air is a fluid. Mechanical waves in air can only be longitudinal in nature; and therefore, all sound waves traveling through air must be longitudinal waves originating in the transmission form of compression and rarefaction from vibrating matter in the medium. The propagation of sound in absence of any material medium is always impossible. Therefore, sound does not travel through the vacuum of outer space, since there is nothing to carry the vibrations from a source to a receiver.
Introduction To Acoustics presents several aspects of the innovative trends ongoing in this field. Theoretical efforts are leading to a deeper understanding of phenomena, also in complicated environments like the solar surface boundary. The field of acoustic engineering has several potential applications, such as in ocean science research and homeland security. This book provides state of the art information in current techniques and technologies, such as the adaptive technique for communication, array processing systems.
Discussing various new issues and developments in different areas of acoustics, it will appeal to researchers and engineers in the field.
