COVER STORY
MAKING A NOISE ABOUT DOSIMETERS
By providing accurate, real-time data on noise exposure, noise dosimeters empower employers to comply with legal regulations, protect worker health, and foster a safer work environment, says Cirrus Research.
Occupational noise-induced hearing loss remains one of the most prevalent and irreversible workplace hazards, affecting millions of workers globally. Despite advances in hearing protection and awareness campaigns, many industries still struggle to effectively manage noise exposure. In this context, noise dosimeters, such as the doseBadge from Cirrus Research, have emerged as indispensable tools in safeguarding workers from the harmful effects of excessive noise.
UNDERSTANDING THE RISKS OF OCCUPATIONAL NOISE Exposure to high levels of noise over prolonged periods can result in permanent hearing damage. This damage, often gradual and unnoticed until it is too late, includes conditions such as tinnitus, temporary threshold shifts, and, ultimately, permanent hearing loss. The psychological and physiological effects of noise exposure can also extend beyond hearing loss, contributing to increased stress levels, reduced productivity, and heightened risks of workplace accidents.
Certain industries – such as construction, manufacturing, mining, and transportation–are particularly prone to elevated noise levels. For workers in these sectors, noise is not just a nuisance but a daily reality that threatens their wellbeing. Therefore, monitoring and mitigating noise exposure is not merely a legal obligation but a moral responsibility for employers.
THE ROLE OF NOISE DOSIMETERS Noise dosimeters are wearable devices designed to measure an individual’s noise exposure over a working shift. Unlike traditional sound level meters, which measure noise at a fixed point, dosimeters travel with the worker, providing a personalised and comprehensive understanding of noise exposure. This capability makes them especially valuable in dynamic and noisy environments where workers move between different noise zones.
The doseBadge, a leading noise dosimeter from Cirrus Research, exemplifies the innovation in this field. Lightweight, robust, and wireless, the doseBadge allows workers to carry out their tasks unhindered while accurately capturing noise exposure data. The absence of cables and external controls reduces the risk of tampering and damage, ensuring reliable measurements in even the harshest environments.

COMPLIANCE WITH LEGAL REGULATIONS Governments and regulatory bodies worldwide have established stringent occupational noise limits to protect workers. In the UK, for example, the Control of Noise at Work Regulations 2005 mandates that employers must take action when noise exposure reaches certain thresholds: 80dB(A) as the lower exposure action value and 85dB(A) as the upper exposure action value. Failure to comply with these regulations can result in hefty fines, legal repercussions, and reputational damage.
Noise dosimeters play a crucial role in ensuring compliance with these regulations. By accurately measuring noise exposure, devices like the doseBadge help employers identify high-risk areas and workers who are at risk of exceeding permissible noise limits. This data serves as the foundation for implementing effective noise control measures, such as engineering controls, administrative changes, or the provision of appropriate hearing protection.
EMPOWERING EMPLOYERS AND WORKERS The value of noise dosimeters extends beyond compliance. They empower employers to adopt a proactive approach to noise management, enabling data-driven decision-making. With the detailed insights provided by devices like the doseBadge, organisations can:
Identify noise hazards: Pinpoint noise sources and trends in workplace noise levels.
Evaluate control measures: Assess the effectiveness of noise reduction interventions and adjust strategies accordingly.
