  • Human factors – Lighting

    Vibration – Whole body vibration (such as experienced in vehicle cabs) can contribute to lower back pain and fatigue. Some frequencies of vibration can have a negative effect on visual performance. Relatively uncommon effects of low frequency vibration (infrasound) can include throbbing in the head (7Hz) and temporary depressed psychological .

  • Waves & Vibrations

    Waves are a wiggle in space cause by a vibration or disturbance. They have the ability to carry energy from one location to another. There are two different types of waves; transverse and longitudinal. A transverse wave is when the wave is vibrating perpendicular to the direction the wave is traveling.
