Protect your team with 5 noise safety program items

While a sudden incident like an explosion can cause immediate damage, the more common threat involves sustained exposure. More often, work-related hearing loss is caused by long-term exposure to excessive noise, like machine noise, that is present throughout a work shift, according to WorkSafeBC. This distinction is critical for owners and team leads because it dictates different control strategies. A single event requires immediate hazard mitigation and emergency response protocols, whereas long-term exposure demands ongoing monitoring and consistent use of hearing protection.

The scope of this guide covers five specific program items: exposure limits, audiometric standards, protection selection, regulatory basis, and program requirements. You cannot manage what you do not measure, so identifying whether a task involves a single high-impact event or continuous machine noise is the first step. For example, a technician servicing a large industrial compressor may face long-term exposure, while a technician handling pressurized systems might face single-event risks.

Review your current job site assessments to identify which tasks exceed safe noise levels and require hearing protection.

• Give your technicians the chance to pick their hearing protectors from a range of suitable options supplied by your company, as required by Legal Information Institute.
• Ensure every worker exposed to hazardous noise participates in a hearing loss prevention program, a mandate stated by WorkSafeBC.
• Consider engineering controls that lower ambient noise to safe levels, which WorkSafeBC notes may remove the necessity for a formal hearing program and protective gear.
• Limit the duration of exposure by restricting the time employees spend near loud equipment, an alternative strategy identified by WorkSafeBC.
• Integrate these four actions into your daily dispatch routines to maintain compliance and protect hearing health.

Noise safety rules vary by jurisdiction, so your program must match the laws where your technicians work.

In the United Kingdom, the Health and Safety Executive notes that the Control of Noise at Work Regulations 2005 replace the Noise at Work Regulations 1989, according to Health and Safety Executive. The Health and Safety Executive explains that both the 1989 and the 2005 sets of noise regulations are based on European Union Directives requiring similar basic laws throughout the Union on protecting workers from the health risks caused by noise, according to Health and Safety Executive.

The Health and Safety Executive further states that the 2005 Noise Regulations replaced the 1989 Noise Regulations and introduced new requirements for action to be taken by employers, according to Health and Safety Executive.

When building your safety program, remember that regulations are not one-size-fits-all. The Legal Information Institute’s rule applies specifically to the U.S. context described in 29 CFR § 1910.95, while the Health and Safety Executive’s rules apply to the UK context. Do not treat one publisher’s rule as every firm’s rule, and do not treat one jurisdiction’s rule as the rule everywhere. Your first step is to identify which regulatory framework governs your specific operating locations.

The table below lists the five core program items with their specific regulatory facts. Each row names the publisher that states the rule, ensuring every requirement is tied to its source.

If you work around hazardous noise, you must take part in a hearing loss prevention program, according to WorkSafeBC. Compliance with the Noise Regulations will allow workers' hearing to be protected, according to Health and Safety Executive.

To build this program, you must verify that your team has the right gear and is using it correctly. Ask yourself: Do workers have appropriate hearing protection that fits them, according to WorkSafeBC? You must also confirm that workers are wearing their hearing protection properly, according to WorkSafeBC.

Before you rely on protectors, consider reducing the source of the problem. Bringing noise down to a safe level may eliminate the need for a hearing loss prevention program and hearing protection, according to WorkSafeBC. This is your first line of defense. If you cannot lower the noise level, you have another option: reduce exposure duration by limiting the time spent around noise, according to WorkSafeBC.

The regulatory basis for protector selection is clear. According to Legal Information Institute, employees shall be given the opportunity to select their hearing protectors from a variety of suitable hearing protectors provided by the employer. This rule establishes that the employer must provide the options, but the choice belongs to the worker.

The right to choose

When you equip your team, you must present multiple options. The requirement is not to provide one type of protector and force compliance. Instead, you must offer a variety of suitable devices. According to Legal Information Institute, the selection process is a mandatory part of the program. This ensures that technicians can find a protector that fits their specific needs and comfort levels.

Practical steps for selection

To implement this, you should stock a range of hearing protectors. This variety allows each technician to choose what works best for them. The employer’s role is to provide these suitable options. According to Legal Information Institute, the opportunity to select is a key component of the safety framework. You should review your inventory to ensure it meets this standard.

Fitting and suitability

Suitability is critical. The protectors provided must be suitable for the noise levels your team encounters. According to Legal Information Institute, the employer is responsible for providing these suitable protectors. This means you must assess the noise environment and choose protectors that offer adequate protection. Do not assume that one size fits all. Offer different types, such as earplugs and earmuffs, to accommodate individual preferences.

Training on selection

Train your technicians on how to select and use their protectors. They need to understand the options available to them. According to Legal Information Institute, the right to select is tied to the provision of suitable protectors. Ensure your training covers this right. Explain that they have the opportunity to choose from the variety you provide.

Reviewing your program

Check your current hearing protection program. Are you providing a variety of suitable protectors? According to Legal Information Institute, employees must be given the opportunity to select. If you are only providing one type, you may not be compliant. Update your inventory and training materials to reflect this requirement.

Action step

Update your inventory to include a variety of suitable hearing protectors so employees can select from the options provided.

To understand when a test result triggers further action, you need to know the specific definition of a hearing change. According to Legal Information Institute, a standard threshold shift is a change in hearing threshold relative to the baseline audiogram of an average of 10 dB or more at 2000, 3000, and 4000 Hz in either ear. This specific metric allows you to track individual technician progress against their initial baseline.

When scheduling these tests, ensure the clinic uses the correct methodology. The regulations specify that audiometric tests shall be pure tone, air conduction, hearing threshold examinations, with test frequencies including as a minimum 500, 1000, 2000, 3000, 4000, and 6000 Hz, according to Legal Information Institute. You can instruct your testing provider to include these specific frequencies in the appointment details. For the calibration check of the audiometer itself, test frequencies below 500 Hz and above 6000 Hz may be omitted from this check, as noted by Legal Information Institute.

Calibration accuracy is critical for valid results. If the equipment shows deviations of 10 decibels or greater, an acoustic calibration is required, according to Legal Information Institute. This rule applies to the testing equipment used to generate the audiograms.

When managing the data from these tests, the decibel unit is a standard way to handle information. The use of dB unit makes it easy to deal with the workplace noise level data provided we use a set of simple rules as summarized in Table 3, according to Canadian Centre for Occupational Health and Safety. Using this unit system helps you compare exposure levels across different job sites and tasks.

To keep your records organized, you can use a simple worksheet to track the key metrics from your audiometric results.

What is a standard threshold shift in hearing tests?

A standard threshold shift is defined as a change in hearing threshold relative to the baseline audiogram.
