Vibration\u00a0is a mechanical phenomenon whereby\u00a0<\/strong>oscillations<\/strong>\u00a0occur about an\u00a0<\/strong>equilibrium point<\/strong>. <\/strong><\/p>\n

Vibration can be desirable or .undesirable, (wasting\u00a0energy\u00a0and creating unwanted\u00a0sound). For example, the vibrational motions of\u00a0engines,\u00a0electric motors, or any\u00a0mechanical device\u00a0in operation are typically unwanted.<\/p>\n

The studies of sound and vibration are closely related. Sound, or pressure\u00a0waves, are generated by vibrating structures; these pressure waves can also induce the vibration of structures. Hence, attempts to reduce noise are often related to issues of vibration. Vibration is calculable by an accelerometer. This device measures acceleration, speed and width oscillation transmitted on the body.<\/p>\n

Some example:<\/p>\n\n\n\n\n\n
Ship\/ plane<\/td>\n2 Hz<\/td>\n<\/tr>\n
Tractor\/bus\/subway<\/td>\n20 Hz<\/td>\n<\/tr>\n
Pneumatic drill\/ milling machine<\/td>\n40 Hz<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Vibration are transmitted through skeleton in human body. Low frequency are more tolerated than high (considered intolerable).<\/p>\n

Vibration perception change with the frequency, like acceleration:<\/p>\n\n\n\n\n\n\n
Description<\/strong><\/td>\nFrequency 1-10 Hz<\/strong><\/p>\n

max. acceleration (mm\/s2<\/sup>)<\/strong><\/td>\n
