Product Overview

Summary: This Noise Monitoring Safe Operating Procedure provides a clear, defensible framework for measuring, recording and managing workplace noise in line with Australian WHS requirements. It helps organisations identify hazardous noise exposure, protect workers from noise-induced hearing loss, and demonstrate compliance to regulators, clients and auditors.

Excessive workplace noise remains one of the most common—and most preventable—causes of permanent hearing loss in Australian workplaces. This Noise Monitoring Safe Operating Procedure establishes a consistent, step-by-step method for planning, conducting and reviewing noise surveys across your operations. It guides you through when monitoring is required, how to select and use calibrated noise monitoring equipment, how to collect reliable data, and how to interpret results against Australian exposure standards.

Designed specifically for the Australian WHS landscape, this SOP helps businesses bridge the gap between legislative obligations and day-to-day practice on site or in the workshop. It supports the development of a robust hearing conservation program by defining roles and responsibilities, documenting repeatable measurement techniques, and integrating monitoring outcomes into risk assessments, engineering controls and hearing protection programs. By implementing this procedure, you can confidently demonstrate due diligence, reduce the risk of workers’ compensation claims related to hearing loss, and provide clear evidence of compliance during audits, inspections and client prequalification processes.

Key Benefits

• Ensure consistent, legally defensible noise monitoring practices aligned with Australian WHS legislation and standards.
• Reduce the risk of noise-induced hearing loss and associated workers’ compensation claims through early identification of hazardous noise areas.
• Demonstrate compliance to regulators, clients and auditors with clear, traceable monitoring records and documented methodologies.
• Support informed decision-making on engineering controls, administrative controls and hearing protection selection using accurate noise data.
• Streamline scheduling, conducting and reviewing noise surveys across multiple sites or departments with a standardised procedure.
