Risvolto di copertina:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sound from ultrasound is the name given here to situations when modulated ultrasound can make its carried signal audible without needing a receiver set. This happens when the modulated ultrasound passes through anything which behaves nonlinearly and thus acts intentionally or unintentionally as a demodulator. Researchers since the early 1960s have been experimenting with creating directive low-frequency sound from nonlinear interaction of an aimed beam of ultrasound waves produced by a parametric array using heterodyning. Ultrasound has wavelengths much smaller than audible sound and thus can be aimed in a much tighter narrow beam than any traditional audible loudspeaker system.
