Rotary tumbling is more common, simpler, quieter and less expensive than vibratory tumblers. After placement it is compacted by vibratory rollers. There are two main types of rock tumbling&colon; barrel (rotary) tumbling, and vibratory tumbling. Amplitude refers to the distance traveled during each vibratory cycle. Quantitative sensory testing (QST) assesses small fiber function by measuring temperature and vibratory sensation. Sound is propagated by progressive longitudinal vibratory disturbances (sound waves). Vibratory hammers can drive or extract a pile. It is this vibratory motion that produces phonation or voice. Other cut-wire shot applications include tumbling and vibratory finishing. Naturally, the nerve conduction slows with aging and a decreased vibratory sensation is common. They occur because the vocal folds are capable of producing several different vibratory patterns. From various experiments, the elephant larynx is shown to produce various and complex vibratory phenomena. What made Cisco a candidate was his metahuman ability to emit powerful vibratory shock waves. Avalanche himself is immune to the generation of his own vibratory waves. Species vary greatly in visual and vibratory components of courtship.
