Noise Reduction | TE Wire & Cable | Thermocouple Wire

Precaution should be taken during design, engineering and installation to reduce the effects of noise. The type of signal transmitted by the sensor is related to its sensitivity to noise. The lower the voltage level and the higher the impedance of a circuit, the greater the circuits sensitivity to noise of all types.

OSHA Technical Manual (OTM) | Section III: Chapter 5

Be aware that if noise levels are high enough, rotation could increase the chances of hearing loss in more workers. If there is a regular noise level of 90 dB, for example, a healthy worker in the area can rotate into an area with a 50-dB noise level without a substantial increase in risk of hearing loss.
