What is the upper limit setting in a dosimeter typically set at?

The upper limit setting in a dosimeter is typically set at 115 dBA because this level is considered a critical threshold in occupational noise exposure regulation. Sound levels above 115 dBA can pose significant hearing risks and are often associated with potential hearing damage over prolonged exposure. Setting the dosimeter at this level ensures that any noise exposure that exceeds it is clearly recorded and addressed, enabling effective monitoring and management of occupational noise hazards.

This threshold aligns with guidelines established by occupational health authorities, which emphasize the importance of preventive measures in noisy environments to protect workers' hearing. By establishing an upper limit at 115 dBA, dosimeters can help employers and safety professionals identify when intervention is necessary to mitigate risks of hearing loss and maintain worker safety.
