Acoustics is the study of small pressure waves or sound waves in air which can be detected by the human beings. The scope of acoustics is not limited and extended to lower and higher frequencies: ultrasound and infrasound. Acoustics now includes Structural vibrations and perception/travelling of sound is an area of acoustical research, for research purposes acoustics are considered, the propagation fluids like air and water. In such a case acoustics is a part of fluid dynamics. The outmost problem of fluid dynamics is that, the equations of motions are non-linear and this implies that an exact general solution of these equations is not available and need to be developed. Acoustics is a first order approximation in which non-linear effects are neglected. In classical acoustics the generation of sound is considered to be a boundary condition problem. The sound generated by a loudspeaker or any unsteady movement of a solid boundary are examples of the sound generation mechanism in classical acoustics. Turbulence is a chaotic motion dominated by non-linear convective forces but an accurate deterministic description of turbulent flows is not available, The famous Lighthill theory of sound generation by turbulence is used as an integral equation which is more suitable to produce approximations than that of a differential equation Next to Lighthill’s approach which leads to order of magnitude estimate of sound production by complex flows. In this paper we produced the application of Acoustics, experiments, research done to utilize the benefits of the acoustics are reviewed much more in a better way to conceptually understand the concept and to deduce the equations of motion to build practical acoustics system and also concentration gone through the Acoustic refrigeration system.
