Smooth pursuit of small-amplitude sinusoidal motion

motion created by the head movements were too high to be tracked even though the amplitude of the motions was small, and, as a result, velocity and acceleration were low. Previous studies3-'0 of smooth pursuit cannot choose be-tween these alternatives, because the response to small-amplitude motions in the frequency range of natural head

Characteristics Of Sound Waves: Amplitude, .

Amplitude refers to the distance of the maximum vertical displacement of the wave from its mean position. Larger the amplitude, the higher the energy. In sound, amplitude refers to the magnitude of compression and expansion experienced by the medium the sound wave is travelling through. This amplitude is perceived by our ears as loudness.
