Discomfort in Whole-body Vibration
A new methodology for objective evaluation of discomfort in whole-body vibration (WBV) is introduced in this work. The proposed objective discomfort characterizes discomfort based on the relative motion between adjacent segments of the human body from neutral positions. It peaks when the joints reach their limits. The objective discomfort has been tested on five subjects in the fore-aft directi...
متن کاملCombined Effects of Long-Term Sitting and Whole-Body Vibration on Discomfort Onset for Vehicle Occupants
Occupants of automobiles experience discomfort after long drives, irrespective of how well designed a seat might be. Previous studies of discomfort during driving have focused either on the seat shape andmaterials (“static” properties), long-term discomfort (“fatigue” properties), or dynamics (“vibration” properties).These factors have previously not been considered together.This paper reports ...
متن کاملThe discomfort produced by noise and whole-body vertical vibration presented separately and in combination.
This study investigated the prediction of the discomfort caused by simultaneous noise and vibration from the discomfort caused by noise and the discomfort caused by vibration when they are presented separately. A total of 24 subjects used absolute magnitude estimation to report their discomfort caused by seven levels of noise (70-88 dBA SEL), 7 magnitudes of vibration (0.146-2.318 ms(- 1.75)) a...
متن کاملThe Effects of Noise and Whole Body Vibration on Urinary Metanephrine and Normetanephrine
Background and Aim: Little attention has been paid to the effects of combined exposure to noise and vibration. Exposure to noise and vibration can effect stress hormones and may lead to high blood pressure and cardiovascular disorders. This study aims to investigate the effects of noise and vibration on urinary Metanephrine and Normetanephrine among men. Methods: In this experimental study, 30 ...
متن کاملResponse of the seated human body to whole-body vertical vibration: discomfort caused by mechanical shocks.
The frequency dependence of discomfort caused by vertical mechanical shocks has been investigated with 20 seated males exposed to upward and downward shocks at 13 fundamental frequencies (1-16 Hz) and 18 magnitudes (±0.12 to ±8.3 ms-2). The rate of growth of discomfort with increasing shock magnitude depended on the fundamental frequency of the shocks, so the frequency dependence of equivalent ...
