Acoustic Waves Generated by Parametric Array Loudspeakers

• Gebundenes Buch

Produktbeschreibung

Parametric array loudspeakers (PALs) are capable of generating highly directional audio beams from nonlinear interactions of intense airborne ultrasound waves. This book systematically introduces the physical principles of acoustics waves generated by PALs, along with the commonly used and the state-of-the-art numerical models.
