Abstract: The well being of people needs to be a priority in the modern world.
In that respect, vibration cannot be one more cause of stress. Besides that,
vibration comfort is very important, since high levels may cause health or even
tasks' accomplishment problems. Several parameters may influence the levels of
vibration a human being supports. Among them, one can mention the influence of
gender, age, corporeal mass index (CMI), temperature, humor, anxiety, hearing,
posture, vision, etc. The first three parameters mentioned were already
investigated in previous studies undertaken by GRAVI (Group of Acoustics and
Vibration) researchers. In this paper, the influence of vision is evaluated.
The main objective with this series of tests performed is to try to quantify in
a future the influence of each parameter in a global vibration comfort level.
Conclusions are presented for the parameter investigated.
Keywords: Human vibration comfort, vision, perception threshold, maximum acceptable vibration, and whole-body vibration
