How Excessive Workplace Noise
Affects Employee Health
Workplace noise is a common occupational hazard in industries such as manufacturing, logistics, construction. Authorities set standards and develop regulations to protect employees’ health and to reduce noise pollution. However, even though organizations stay compliant with the permissible noise exposure limit, employees’ physical health and work performance may be impacted.
Therefore, consistent & professional industrial noise monitoring is important for organizations to track the impact of workplace noise and develop effective safety measures.
How Excessive Workplace Noise Affects Employee Health
Workplace noise is a common occupational hazard in industries such as manufacturing, logistics, and construction. Authorities set standards and develop regulations to protect employees’ health and to reduce noise pollution. However, even though organizations stay compliant with the permissible noise exposure limit, employees’ physical health and work performance may be impacted. Therefore, consistent and professional industrial noise monitoring is important for organizations to track the impact of workplace noise and develop effective safety measures.
Understanding Workplace Noise Exposure
Workplace noise refers to harmful sound in the workplace that employees are exposed to during their shift. These may arise from various sources such as machinery, tools, and operations. Some industrial noise is continuous while others may be sudden and irregular.
In Singapore, the permissible workplace noise exposure limit is 85 dB(A) over an 8-hour workday according to Workplace Safety and Health (WSH) Regulations. One thing is that even if companies keep the noise exposure below the limit, noise-related risks can still occur. Therefore, companies need to conduct regular industrial noise monitoring and implement proper noise control measures to stay compliant.
Risks of Workplace Noise
Hearing Issues
Noise-Induced Hearing Loss (NIHL) is one of the most common health issues caused by workplace noise. Since hearing deterioration begins at higher frequencies, many people miss it in its early stages. NIHL is a chronic hearing problem and it may develop gradually if employees are exposed to significant noise without proper control activities.
Operational Risks
Besides direct health issues, workplace noise can also interfere with communication at the workplace, leading to operational risks. In high-risk working environments, potential accidents and injuries may occur.
Regulatory and Financial Risks
In Singapore, if employees are exposed above the permissible noise exposure limit, organizations need to conduct noise monitoring regularly and implement proper protective controls in accordance with WSH regulations. If employees’ occupational health concerns and issues develop, organizations may face fines, penalties, and insurance claims.
Psychological and Cognitive Effects
Reduced Focus
Hearing industrial noise can make it difficult for employees to concentrate on their work and make accurate decisions.
As a result, organizations may receive less accurate results. Especially in industries that require precise attention like manufacturing, the impact of risk can be more intense.
Mental Workload
When working in a noisy environment, the worker’s brain needs to put extra effort to filter unwanted noise and focus on the task. As the mental workload is increased, employees exposed to loud noise can get overwhelmed easily and increase potential errors.
Stress Response
Studies have suggested that excessive workplace noise may contribute to increased stress, irritation, and discomfort among employees.
Role of Workplace Noise Monitoring
Workplace noise monitoring is systematically monitoring and assessing the noise level within the workplace. The purpose of noise monitoring is to verify regulatory compliance, check the requirement for protective activities, and identify noise-related risks.
Professionals use professional noise monitoring equipment and structured assessment approaches to identify and evaluate workplace noise levels. As industrial noise monitoring offers objective results, organizations can use this information to develop and implement effective noise management plans.
Develop a Safer Workplace
Organizations use various methods to control and prevent potential risks arising from occupational noise.
(1) Engineering Controls: Recommended engineering controls may include machine maintenance, installation of sound barriers, equipment repositioning, or other suitable noise reduction measures.
(2) Administrative Controls: Changing management decisions regarding employees’ workflow is also common. Organizations can rotate shifts to reduce noise exposure duration and schedule noisy processes when fewer workers are present.
(3) Health Protection Plan: Organizations can prepare proactive plans to protect workers from hearing issues. This may include providing protection tools, educating workers on potential noise-related risks, testing workers’ hearing ability, and conducting workplace noise monitoring regularly.
