Human Effects when Exposed to Low-Frequency Noise or Vibration

Physiological effects from low-frequency noise or vibrations.

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
