Noise Exposure & Noise Risk Assessment (NRA)

Noise exposure refers to the level of sound energy a person is subjected to over a specific period of time. This exposure is measured in decibels (dB) and is typically evaluated using instruments such as sound level meters. Both the intensity and duration of exposure are critical in determining the potential health effects on individuals in the workplace.

A sound level meter is commonly used to monitor ambient noise levels in various areas of a workplace. For more detailed and personal exposure data, a dosimeter is often utilized, particularly during a Noise Risk Assessment (NRA). This assessment is essential in identifying areas within the workplace that pose excessive noise risks, enabling proactive measures to protect workers' hearing.

Sound Level Meter (SLM) is used to take exposure data as part of the Noise Risk Assessment (NRA) to identify excessive noise levels in the workplace.

According to the Occupational Safety and Health (Noise Exposure) Regulations 2019, employers are responsible for assessing and controlling excessive noise levels in the workplace to prevent hearing damage and ensure the safety of their employees. A Noise Risk Assessment (NRA) plays a crucial role in complying with these legal requirements.

The key noise exposure limits typically evaluated during an NRA include:

• Daily noise exposure level: 85 dB(A)

• Maximum sound pressure level (any time): 115 dB(A)

• Peak sound pressure level: 140 dB(C)

When noise exposure exceeds these limits, it can lead to several adverse effects, including:

• Hearing loss or impairment

• Increased work-related stress

• Decreased worker productivity

• Difficulty in communication and maintaining focus

• Inability to hear alarms or warning signals

• Higher risk of workplace accidents and injuries

To reduce the risk of hearing damage, employers can implement several preventive measures, such as:

• Reducing exposure duration through job rotation

• Increasing the distance between workers and noise sources

• Scheduling tasks to minimize the number of workers in noisy areas

• Limiting the number of employees exposed at any one time

• Providing regular rest breaks in quiet zones

• Supplying suitable personal hearing protection

• Implementing engineering controls to isolate noise sources

Using a dosimeter, personal noise monitoring can be conducted effectively to gather accurate exposure data for individual employees. This is a key step in any Noise Risk Assessment (NRA) process.

In summary, identifying and controlling sources of excessive noise in the workplace is vital in preventing long-term hearing problems and maintaining a safe, productive work environment. A comprehensive Noise Risk Assessment (NRA) ensures that employees are not exposed to hazardous noise levels during their duties.

Noise Risk Assessment (NRA) in Malaysia

In accordance with the Occupational Safety and Health (Noise Exposure) Regulations 2019;

Role of the Noise Risk Assessor in Noise Risk Assessment (NRA):

The Noise Risk Assessor is the qualified person responsible for conducting the Noise Risk Assessment (NRA) at workplaces as mandated by the Occupational Safety and Health (Noise) Regulations 2019. Employers must appoint a competent NRA to carry out the Noise Risk Assessment (NRA) and ensure compliance with the standards set by the Department of Occupational Safety and Health (DOSH).

The Noise Risk Assessor is providing a briefing to the client on improvement measures to reduce noise levels in the workplace as part of the Noise Risk Assessment (NRA).

Responsibilities of the Noise Risk Assessor during Noise Risk Assessment (NRA):

The NRA must perform the Noise Risk Assessment (NRA) within their valid registration period, ensuring that all noise measuring equipment used is properly calibrated and valid for the assessment. The NRA is also required to notify the Director of the respective DOSH state office at least 14 days before conducting any Noise Risk Assessment (NRA). After completing the Noise Risk Assessment (NRA), the NRA must provide the employer with a detailed report and present recommendations on noise control within 30 days. Additionally, a summary report of the Noise Risk Assessment (NRA) must be submitted to the Director General within the same timeframe.

WHAT IS NOISE RISK ASSESSMENT (NRA)?

Noise Risk Assessment (NRA) is a structured and essential process designed to identify hazardous noise sources in the workplace and evaluate how they affect employees. The key objectives of conducting a Noise Risk Assessment (NRA) are to measure noise exposure levels, define noise-contour zones, monitor individual exposure and recommend effective control measures to protect workers' hearing. Under the Occupational Safety and Health (Noise) Regulations 2019, employers are legally required to appoint or engage a qualified Noise Risk Assessor (NRA) to carry out this assessment in full compliance with safety standards. Tools such as dosimeters are commonly used during the Noise Risk Assessment (NRA) to accurately monitor and record employee noise exposure throughout their working hours.

The assessor is collecting noise data during area monitoring as part of the Noise Risk Assessment (NRA).

The purpose of a Noise Risk Assessment (NRA) is to identify specific areas in the workplace where noise levels pose a potential risk and to recognize employees who may be exposed to dangerous levels of noise that could lead to hearing damage or loss. By conducting a thorough Noise Risk Assessment (NRA), employers can determine where further measurements are needed and what steps must be taken to control or reduce noise exposure. This process ensures that effective noise control strategies are implemented and that the workplace meets all regulatory requirements for occupational noise exposure.

Our Noise Risk Assessment (NRA) services are tailored to identify noise-related hazards and assess which employees are most at risk. Through a detailed evaluation, we compare actual noise exposure against legal action values and limits to determine compliance. Based on the results of the Noise Risk Assessment (NRA), we provide specific recommendations for suitable hearing protection, noise control measures, and health surveillance for high-risk employees. This helps to ensure a safe and legally compliant working environment.

We are committed to delivering high-quality Noise Risk Assessment (NRA) services that are accurate, reliable and aligned with regulatory standards. Whether you need to assess a new facility or update an existing report, our team is ready to support your needs.
