Noise at Work: NEMS & Dosimetry

Description

Noise Exposure Measurement System (NEMS)

The Control of Noise at Work Regulations imposes a legal obligation on employers to prevent damage to the hearing of employees and visitors to their premises. Assessment of noise exposure must be carried out by a competent person. NEMS & Dosimetry is the tool to assess and identify all persons likely to be exposed and provide information to indicate where action is needed and assist in deciding what further action is appropriate.

NEMS & Dosimetry techniques incorporated in undertaking a noise survey include the use of personal dosimetry to measure an employee’s exposure to noise over a working day, spot reading of sound pressure levels from various machines/locations, and the calculation of expected noise exposure based on duration spent in particular locations or carrying out specific tasks.
