Occupational Noise Monitoring & Services

HAZCON can identify and measure noise sources in your workplace to assess what action is needed to be compliant with the legislation in your state or jurisdiction.

HAZCON can assist you:

Assess your employees' individual or Similar Exposure Groups (SEGs) noise exposure;
Develop a range of control measures to minimise noise exposure in a cost effective way;
Develop policy (hearing protection for specific tasks, occupations and/or environments, assessing new equipment purchases);
Assess new equipment once installed;
Evaluate the effectiveness of Hearing Protective Devices (HPD);
Provide advice on required HPDs available and the type most suitable for the occupation and/or environment; and
Train staff in the correct use of PPE.

The SafeWork Australia sets two noise limits. The first is that no employee should be exposed to an eight hour equivalent continuous sound pressure level greater than 85dB(A) and second, no employee should be exposed to peak levels in excess of 140 dB.

Where it is suspected that employees may be exposed to noise in excess of the exposure standards, the employer must determine the level of exposure. The employer should also re-assess employees' noise exposure if previous assessments are no longer applicable or if requested by the Health and Safety Representative.

Workplace Noise Assessment /Noise Monitoring

Noise assessments are undertaken by attaching noise monitoring equipment (dosimeters) to a number of representative employees at the workplace. The dosimeters are worn by the employees for a minimum of four hours; or preferably for the entire shift. The noise data collected is then analysed to determine employees' eight hour exposure level and their peak noise exposure.

All of HAZCONs activities and recommendations are undertaken in compliance with appropriate legislation, Australian Standards and best practice. Noise monitoring is carried out in accordance with the:
