This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Parametric array loudspeakers (PALs) are capable of generating highly directional audio beams from nonlinear interactions of intense airborne ultrasound waves. This unique capability holds great potential in audio engineering. 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, such as the Westervelt model, the convolution directivity model, the Gaussian beam expansion method, and the spherical wave expansion method. The book is tailored to meet the needs of researchers in this field, as well as audio practitioners and acoustics engineers"--
