Noise pollution is a significant hazard in mining and industrial sectors, posing a threat to worker health and safety. Exposure to excessive noise can lead to permanent hearing loss, stress, and other health complications.

Recognising this issue, Probe IMT says it is implementing advanced noise monitoring solutions from Canadian monitoring specialists M3SH Technology to foster healthier, safer and more productive work environments in the mining sector.

Noise monitoring in mining and industrial operations is crucial from a health and safety perspective for several reasons:

• Prevention of noise-induced hearing loss: Prolonged exposure to high noise levels can lead to permanent hearing loss. By monitoring noise levels, companies can identify areas where noise reduction measures are needed, such as installing noise barriers or implementing quieter machinery or processes.
• Compliance with regulations: Many countries have strict regulations regarding permissible noise levels in the workplace. The Mine Health and Safety Act of South Africa outlines various guidelines and regulations to protect miners’ hearing. Regular noise monitoring ensures that mining operations are in compliance with these standards, thereby safeguarding workers’ health and avoiding penalties.
• Reduction of non-auditory health effects: Excessive noise can contribute to other health issues such as stress, sleep disturbances, cardiovascular diseases, and mental health problems. Effective noise monitoring helps in mitigating these risks.
• Improved communication and safety: A study on noise exposure levels in South African mining found that excessive noise exposure in the workplace can limit workers’ ability to communicate and hear warning signals, affecting safety. By keeping noise levels within acceptable limits, mining operations can ensure clear communication and thus enhance overall safety.
• Worker comfort and productivity: Monitoring and controlling noise levels can help to create a more conducive working environment, which can boost morale and improve productivity and efficiency.

Known as the Noise Monitor Series, M3SH Technology’s product range is designed to provide real-time, accurate noise level data. The solution is particularly suited for demanding industrial environments such as mining, large industrial spaces, workshops and yards, where it can be used to track and monitor noise levels.

The system is available in both portable and fixed models and can record a range of noise metrics. The devices support remote access, allowing users to control settings and access data remotely. A notable feature is a warning-light notification display, available in two sizes, which visually alerts workers when noise levels reach potentially harmful thresholds.

Built with rugged construction and IP-rated enclosures, the monitors are designed to withstand harsh environmental conditions, including vibration, dust and moisture. They also have a wide operating temperature range, making them suitable for various mining contexts.

The Noise Monitor Series devices include advanced connectivity options and feature built-in Wi-Fi for data transmission, enabling real-time monitoring, immediate alerts, and timely response to potential noise hazards.

The NM Noise Monitoring System has up to five wireless node-feeder sensors that can be strategically placed to monitor noise levels throughout a given area. The sensors are linked to a central display controller that provides real-time noise level data, which can be used to alert workers when hearing protection gear is required.
