Noise Hazard Identification and Evaluation Checklist
Based on

How to Use This Checklist

  • **Work through the noise hazard indicators.** Answer each question with Yes, No, or Not applicable. Start with the everyday indicators: whether it is necessary to raise your voice to communicate with someone at one meter distance, whether employees use noisy power tools or machinery, and whether there are impact noises from explosive sources.
  • **Record the hearing-related indicators.** Note whether workers complain that noise prevents them from clearly hearing instructions or warning signals, whether they experience ringing in the ears, blurred hearing, or sound heard differently in each ear, and whether any employee has started experiencing hearing difficulties after working here.
  • **Check equipment information and existing noise records.** Look for manufacturer information, including labels, indicating noise levels exceeding a maximum sound pressure level of 140 dB(C) or a sound pressure level of 82 dB(A), and review results from previous noise studies for levels exceeding 85 dB.
  • **Assess the controls already in place.** Record where personal hearing protectors are used for some jobs, and whether acoustic barriers, machine enclosures, or sound-absorbing materials are used to minimize noise.
  • **Look at the wider record.** Note whether there are visible warning signs related to noise hazards, whether any claim for industrial deafness has been made, whether any long-term employees have hearing problems, and whether the latest noise risk assessment indicates exposure to the noise exposure limit.
  • **Capture anything else that points to a noise hazard.** If any other incident makes you think there may be an existing noise hazard, add a note to provide context.
  • **Close out the review.** Record corrective actions and next steps, other comments and recommendations, and your signature, then complete the completion details: the time you finished, and the actual start and end dates of the inspection.

What noise hazard identification and evaluation is

Noise hazard identification means examining a workplace to find where sound may be harming the people who work in it, and judging whether that risk needs further evaluation and management. The Noise Hazard Identification and Evaluation Checklist works through the indicators that point to a noise problem. You answer each indicator with Yes, No, or Not applicable so that the record is consistent whoever completes it. The process is deliberately practical. It covers observable signs, such as whether it is necessary to raise your voice to communicate with someone at one meter distance, whether employees use noisy power tools or machinery, and whether there are impact noises from explosive sources. It then covers what workers report, including complaints that noise prevents them from clearly hearing instructions or warning signals, and symptoms such as ringing in the ears, blurred hearing, or sound heard differently in each ear. It also asks whether any employee has started experiencing hearing difficulties after working here, and whether any long-term employees have hearing problems.

Why it matters

Exposure to loud noise can damage hearing, and the damage is often noticed only after it has occurred. The checklist includes indicators that point to this: whether a claim for industrial deafness has been made, and whether employees notice a reduction in hearing throughout the day, for example having to turn up the volume of the radio or music playlist on the way home. Noise also affects safety in the moment. Workers who say there is so much noise they cannot clearly hear instructions or warning signals cannot rely on those signals to keep them safe. Identifying noise hazards gives you a documented picture of the problem and where it occurs, so that decisions about controls, hearing protection, and further assessment rest on evidence rather than assumption.

What a good noise hazard review covers

A complete review looks at the source, the people exposed, and what is already being done about it. - **The source of the noise.** Power tools and machinery, impact noises from explosive sources, and equipment carrying manufacturer information, including labels, indicating noise levels exceeding a maximum sound pressure level of 140 dB(C) or a sound pressure level of 82 dB(A). - **The human indicators.** Whether it is necessary to raise your voice at one meter, whether workers cannot hear instructions or warning signals, whether they experience ringing in the ears, blurred hearing, or sound heard differently in each ear, and whether any employee has begun experiencing hearing difficulties after working here. - **The existing controls.** Whether personal hearing protectors are used for some jobs, and whether acoustic barriers, machine enclosures, or sound-absorbing materials are used to minimize noise. - **The documented record.** Whether there are visible warning signs related to noise hazards, whether results from previous noise studies indicate noise levels exceeding 85 dB, and whether the latest noise risk assessment indicates exposure to the noise exposure limit. - **The history.** Whether there has been any claim for industrial deafness, and whether any long-term employees have hearing problems. - **Anything else.** If any other incident makes you think there may be an existing noise hazard, add a note to provide context.

How to carry out the review

The checklist is organized into two sections: the Noise Hazard Indicators Checklist and Completion. The Noise Hazard Indicators Checklist contains the substance of the review. Start by noting when the inspection was conducted, who prepared it, and the location, then work through each indicator in turn and record Yes, No, or Not applicable. Where a question asks for a note, such as the prompt to add context if any other incident suggests an existing noise hazard, record that context in the space provided. When the indicators are complete, use the Completion section to set out corrective actions and next steps, other comments and recommendations, and your signature. Finish by recording the time the inspection was completed and the actual start and end dates, so the record is traceable to the day it was made. The findings of the identification step are the input to further risk evaluation and management. Where the indicators point to a problem, the documented answers give you the basis for deciding what to assess in more detail and what to change.

Where it fits alongside regulation and good practice

Noise at work is an area that many employers are expected to manage as part of their general duty to provide a safe workplace. In the United States, the Occupational Safety and Health Administration (OSHA) addresses occupational noise exposure. In Australia, workplace health and safety legislation places duties on persons conducting a business or undertaking to manage risks to health and safety, and noise that may harm hearing falls within that duty. Other countries have their own requirements, and some apply further controls such as surveillance means like audiometric testing under specific legislation. This checklist does not replace those requirements or a full noise risk assessment. It is a structured identification and evaluation tool: it helps you recognize the indicators of a noise hazard, capture what you find, and record the controls already in place, so that any further assessment or management step is grounded in what the workplace actually shows.

Frequently Asked Questions

Deciding whether a noise problem exists does not require a sound level meter, and the checklist starts with observation-based indicators rather than measurements. Work through questions such as whether it is necessary to raise your voice to communicate with someone at one meter distance, whether employees use noisy power tools or machinery, and whether there are impact noises from explosive sources. Capture whether workers complain that noise prevents them from hearing instructions or warning signals, and whether anyone notices ringing in the ears, blurred hearing, or sound heard differently in each ear.

Once a hazard is suggested, the checklist turns to evidence. Check whether any equipment carries manufacturer information, including labels, indicating noise levels above a maximum sound pressure level of 140 dB(C) or a sound pressure level of 82 dB(A). Review results from previous noise studies for levels above 85 dB, look for visible warning signs related to noise hazards, and check whether the latest noise risk assessment indicates exposure to the noise exposure limit. Also review whether any employee has started experiencing hearing difficulties after working here, whether any long-term employees have hearing problems, and whether there has been any claim for industrial deafness.

Existing controls are recorded alongside the hazards. Note where personal hearing protectors are used for some jobs, and whether acoustic barriers, machine enclosures, or sound-absorbing materials are used to minimize noise. Record anything else that makes you think there may be an existing noise hazard, adding a note to provide context, and document any other incident that points to a noise problem.

Every noise hazard indicator is answered Yes, No, or Not applicable, which keeps the record consistent across assessors and sites. Answers are supported by documented findings, and the checklist closes with corrective actions and next steps, other comments and recommendations, a signature, and the completion details including the time the inspection finished and its actual start and end dates. Those findings then feed further risk evaluation and management towards workplace safety.

Noise hazard identification is relevant wherever employees work with or near noisy equipment, processes, or impact sources, or where there are signs that hearing may be affected. The checklist asks about power tools and machinery, explosive impact noises, communication difficulties at close range, hearing symptoms reported by workers, the use of personal hearing protectors for some jobs, and claims of industrial deafness. Warning signs and previous noise study results help confirm whether a fuller assessment is needed.

The checklist is completed by the person carrying out the noise hazard identification. It records who the inspection was prepared by, when it was conducted, and the location, so the findings can be traced to a specific site and time. Completion details include a signature and the actual start and end dates of the inspection.
