A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

The approach uses high-frequency sound waves ... polarization and amplitude of the applied sound wave. This approach offers far more rapid tuning than a mechanical grating, which must be moved ...

The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE. See: SOUND, SPEED OF SOUND ... It should be noted, however, it can be as high as 5 dB/100 m at 8 kHz when the temperature is 20°C ...

This is where two acoustic waves transfer energy to a surface wave by matching its frequency, which in turn causes the ...
