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.

- 1. What is NEMS and Dosimetry training?
NEMS & Dosimetry training teaches professionals how to assess workplace noise exposure using noise measurement systems, sound-level meters, and personal noise dosimeters. - 2. What is a Noise Exposure Measurement System (NEMS)?
NEMS is used to assess workplace noise exposure, identify employees at risk, and determine where additional noise-control measures may be required. - 3. What is noise dosimetry?
Noise dosimetry measures an individual worker’s personal noise exposure over a working period to help determine whether exposure levels require control or protection. - 4. Who should take a Noise at Work NEMS & Dosimetry course?
The course is suitable for professionals involved in workplace safety, industrial operations, offshore and marine environments, and anyone responsible for assessing or managing occupational noise exposure. - 5. What will I learn in NEMS & Dosimetry training?
You will learn about sound and hearing, decibel calculations, noise exposure assessment, noise measurement, sound-level meters, workplace noise regulations, hearing protection, and practical dosimeter operation. - 6. How is workplace noise exposure measured?
Workplace noise can be assessed using sound-level meters, spot measurements, exposure calculations, and personal dosimetry to determine a worker’s exposure during the working day. - 7. What is the difference between a sound level meter and a noise dosimeter?
A sound-level meter measures noise at a particular location, while a personal dosimeter is worn by a worker to measure their noise exposure over a period of work. - 8. Is NEMS & Dosimetry training useful for offshore and industrial workers?
Yes. The training is particularly relevant to offshore, marine, manufacturing, construction, engineering, and other workplaces where employees may be exposed to high noise levels. - 9. How long is the Noise at Work NEMS & Dosimetry course?
Elite Offshore’s NEMS & Dosimetry course is an 8-hour, one-day training program conducted offline. - 10. What standards are covered in the NEMS & Dosimetry course?
The course is conducted in accordance with publicly available BS 4142:2014 and Control of Noise at Work Regulations (CoNAWR): 2005.
