Workplace noise can vary between machines, tasks, work areas and different times of the day. While some noise hazards are obvious, others are difficult to judge without actually measuring them.
Professional noise monitoring services provide reliable information about workplace sound levels, helping identify noisy equipment, higher-risk areas and potential worker exposure.
Verum Group provides area and personal noise monitoring across New Zealand, the Pacific and Asia.
What Is a Decibel Meter Reading?
A decibel meter, more commonly known as a sound level meter, measures sound levels at a particular location.
Readings can be taken around machinery, workshops, construction sites and other work areas to help:
Identify noisy equipment or processes.
Compare noise levels across different areas.
Locate higher-noise zones.
Assess changes after new machinery or controls are introduced.
Determine whether further monitoring is needed.
Is One Decibel Reading Enough?
A single reading provides useful information at a particular place and time, but workplace noise is rarely constant.
Equipment may operate intermittently, workers may move between areas, and some tasks may only create high noise levels for short periods.
For this reason, a workplace noise assessment may involve multiple readings across different locations and activities.
Area Noise Monitoring vs Personal Noise Monitoring
Area noise monitoring uses a sound level meter to measure noise at specific locations and identify noisy machinery, processes and work zones.
Personal noise monitoring involves a worker wearing a dosimeter near their hearing zone while completing normal tasks. This captures how exposure changes throughout the shift.
Using both approaches can provide a clearer picture of workplace noise and worker exposure.
When Is Noise Monitoring Useful?
Noise monitoring may be useful when:
Machinery, tools or processes generate significant noise.
Actual workplace noise levels are unknown.
Workers move between different tasks or areas.
New equipment or processes are introduced.
Noise controls have changed.
A business wants to check whether existing controls are effective.
Turning Noise Measurements Into Action
Noise monitoring should help businesses understand where noise is coming from and how exposure can be reduced.
Depending on the findings, controls may include:
Selecting quieter equipment or processes.
Isolating noisy machinery.
Installing barriers or acoustic enclosures.
Improving maintenance.
Changing work practices or task duration.
Reviewing hearing protection requirements.
Monitoring can also be repeated after controls are introduced to check whether they are working effectively.
Professional Workplace Noise Monitoring
Workplace noise can be difficult to assess by ear alone. Professional monitoring provides objective data about sound levels, noisy areas and worker exposure.
