Human Effects when Exposed to Low-Frequency Noise or Vibration
Physiological effects from low-frequency noise or vibrations.
The physiological effect of low-frequency noise and vibration peak amplitudes on a body:
Comfort Assessments of Vibration Environments
Vibration Level - Acceleration (m/s2) | Human Perception |
---|---|
< 0.315 | Not uncomfortable |
0.315 - 0.63 | A little uncomfortable |
0.5 - 1 | Fairly uncomfortable |
0.8 - 1.6 | Uncomfortable |
1.25 - 2.5 | Very uncomfortable |
> 2 | Extremely uncomfortable |
- 1 m/s2 = 3.28 ft/s2
