Minimise
noise nuisance
to sensitive
receptors
Description of mitigation
• Develop a detailed plan that relates to noise control for
relevant work practices and discuss this with
construction staff during health & safety briefings;
• Avoid dropping materials from height, where practicable;
• Avoid metal-to-metal contact on equipment;
• Avoid mobile plant clustering near residences and other
sensitive land uses;
• Ensure periods of respite are provided in the case of
unavoidable maximum noise level events;
• Inform all potentially impacted residents of the nature of
works to be carried out, the expected noise levels and
duration, as well as providing the contact details of the
CLO;
• Train construction staff on noise control plan during
health & safety briefings;
• Select ‘low noise’ equipment, or methods of work;
• Use most effective mufflers, enclosures and low-noise
tool bits and blades;
• Investigate use of alternatives to audible reversing alarms
(such as broadband noise emitting models) or configure
to maximise forward movements of mobile plant;
• Use alternatives to diesel/petrol engines and pneumatic
units, such as hydraulic or electric-controlled units, where
feasible and reasonable;
• Use temporary noise barriers for small equipment, where
required;
• Reduce throttle settings and turn off equipment and plant
when not used; and
• Regular inspection and maintenance of all plant and
equipment.
