24List of effects — This is a list of names for observable phenonema that contain the word effect, amplified by reference(s) to their respective fields of study. #*3D audio effect (audio effects)A*Accelerator effect (economics) *Accordion effect (physics) (waves)… …
25Parametric array — The parametric array is a nonlinear transduction mechanism that generates narrow, nearly sidelobe free beams of low frequency sound, through the mixing and interaction of high frequency sound waves, effectively overcoming the diffraction limit (a …
26Speed of sound — Sound is a vibration that travels through an elastic medium as a wave. The speed of sound describes how much distance such a wave travels in a certain amount of time. In SI Units with dry air at 20 °C (68 °F), the speed of sound is 343 m/s. This… …
