Audible sound analysis of parametric speaker by concentrated mass model (Steady-state response analysis for cylindrical acoustic space by substructure synthesis method)

Parametric speaker can radiate an audible sound beam with sharp directivity by using the nonlinear interaction of ultrasonic waves.In soderhamn ottoman cover recent years, the highly directional audible sound generated by the parametric speaker has been applied to various applications.For example, applications such as active noise control, sound ab
