Coordinate noise management activities

This unit of competency covers the ability to oversee the day-to-day noise management activities for a site, project or ongoing program. Personnel are required to interpret and implement a noise monitoring plan, organise specified monitoring activities, verify the quality of monitoring data and investigate and rectify unexpected or unacceptable results, monitor compliance with relevant noise standards/limits, and provide reports. They work under the supervision of an environmental scientist or engineer, site manager or enterprise environmental manager.


This unit of competency is applicable to environmental site coordinators, environmental managers and senior environmental officers working in a range of industry sectors, such as:

environmental services involved with sampling, monitoring and/or control of noise

environmental compliance, auditing and inspection.

Note that the term ‘manager’ is used to refer to management of a function, project and/or program and does not necessarily imply line management.
