Design of directional loudspeaker : study of modulation techniques
Nonlinear interaction of ultrasound waves can be applied with parametric loudspeaker to generate audible sound. The audible sound reproduced using parametric loudspeaker has a special characteristic of high directivity. This phenomenon, known as the parametric array, is due to the self-demodulation...
