An alternative method to measure the on-axis difference-frequency sound in a parametric loudspeaker without using an acoustic filter
The self-demodulation characteristic of finite-amplitude ultrasonic sound waves can be applied with parametric loudspeaker to reproduce audible sound with highly directivity. But measuring the difference-frequency sound is still a problem due to the spurious sound generated as a result of nonlineari...
