Manual On The Code Of The Book Entitled Acoustic Waves Generated By The phenomenon of the parametric array, seen first experimentally by westervelt in the 1950s, was later explained theoretically in 1960, at a meeting of the acoustical society of america. More recently, a procedure for optimizing the performance of parametric transmitting arrays by spectral design of the modulating envelope has been outlined in a preliminary study by clynch (ref. 42).
Parametric Array Architizer This book highlights a comprehensive overview of research and technical advances related to parametric array loudspeakers (pals), covering modeling and simulation, measurements, signal processing, beamsteering, and their implementations and applications. The acoustic features of the parametric array in water are basically the same as that in air, with sharp directivity at low frequency and with suppressed side lobes. An efficient method for calculating the nonlinear sound field of a parametric array without additional approximation is proposed, which provides a new approach for calculating the sound field of a parametric array with complex sound sources. We describe a series of measurements to assess the practicality of a length limited parametric array in air. this study shows that the length limited effect is a measurable phenomenon that can be produced using pairs of commercial off the shelf parametric array speakers.

This is where the technology of parametric arrays, often used in creating “sound beams,” comes into play. parametric arrays utilize nonlinear acoustics to generate a highly focused beam of sound that can be directed at specific targets or areas, much like a laser beam in optics. As a sound transmitting device based on the nonlinear acoustic theory, parametric acoustic array (paa) is able to generate high directivity and low frequency broadband signals with a small. As a sound transmitting device that relies on the nonlinearity of a medium, a parametric array (pa) can generate high directivity low frequency signals using a small aperture transducer and high frequency signals. The phenomenon of the parametric array, seen first experimentally by westervelt in the 1950s, was later explained theoretically in 1960, at a meeting of the acoustical society of america.
