PERSONAL NOISE MONITORING (NOISE DOSIMETRY)

Personal noise dosimetry :

​

A noise dosimeter is a small, light device that clips to the lapel of worker near the ear. The dosimeter stores the noise level information and carries out an averaging process. It is useful in industry where noise usually varies in duration and intensity, and where the person changes locations.

 

Legal requirement for personal noise dosimetry :

​

As per Workplace Safety and Health Guidelines - Hearing Conservation Programme 2014, every worker who is exposed to or likely to be exposed to high noise levels shall be included in the noise monitoring exercise. The noise monitoring exercise refers to performing personal noise dosimeter measurement which involves in the measurement of individual workers noise exposure level using personal dosimeter.

 

This requirement was introduced by MOM in their latest version of Workplace Safety and Health Guidelines - Hearing Conservation Programme 2014. As per the guidelines workers shall be grouped based on Similar Exposure Group. Based on the number of personnel in Similar Exposure Group, the number of workers to be involved in personal noise dosimeter measurement shall be determined.

 

Qsafe Pte. Ltd provide the most competent personnel for performing personal noise exposure measurement. Our friendly noise monitoring officers shall assist the occupier’s representative in establishing the Similar Exposure Group, identifying the apt worker for personal noise measurement, installing the personal dosimeter on the workers lapel of worker near the ear, and instructing the safe handling method of the personal dosimeter instrument to the workforce.

 

Frequency of noise measurement :

​

The frequency of noise monitoring is to be in-line with the noise monitoring. I.E. whenever the occupier (factory permit holder) performs the noise mapping, it shall be accompanied with the personal noise dosimeter measurement.

QSafe Pte. Ltd provide the most competent personnel to perform the workplace noise monitoring and personal dosimetry.

 

Purpose of personal noise dosimeter measurement :

​

If a person is exposed over an eight-hour work shift to varying noise levels, then there is an need to calculate an equivalent sound level which would equal the same total sound energy exposure. This would have the same effect on the person's hearing as the variable exposure actually received. Wearing the dosimeter over a complete work shift gives the average noise exposure or noise dose for that person. The purpose of the personal dosimeter monitoring is to get the most accurate noise exposure level of an individual personnel.

 

Submission of noise monitoring report to MOM :

​

As Qsafe Pte. Ltd is an MOM approved noise monitoring company, we shall submit the personal noise dosimeter measurement on behalf of our clients.
