Workplace Noise Measurements for Industrial Safety and Health
The NB-14 noise dosimeter, measures noise exposure for an individual working in a noisy workplace. Measuring and managing noise exposure for individual workers enable early detection and treatment of noise-induced hearing impairment,the adoption of personal hearing protection equipment such as earplugs and earmuffs,and the introduction of effective measures to reduce noise at the source.
