Acoustic scattering is a phenomenon of dispersion of sound which occurs when sound waves strike an obstacle (scatterer). An analytical method has been proposed to investigate the scattered sound field around rigid sphere. Subsequently, scattered sound pressure level has also been investigated for elastic sphere whose results are compared with the results of sound hard sphere having properties of extremely hard wall. Since mathematical solutions for acoustic scattering phenomenon are too incomprehensible for practical cases, limiting cases are primarily considered for the study and the development of mathematical model to reduce the level of complexity. The analysis is therefore embarked with an immovable, solid and rigid spherical acoustic scatterer to reduce the dependency of solution on Bessel function. Sound pressure level has been calculated for two cases; first case is when product of wave number and radius of sphere is far more than unity and in second case product of wave number and radius of sphere is considered far less than unity. In both the cases, sound pressure level has been estimated at lower frequencies which are generally difficult to absorb.
