Noise is a common health hazard in factories. Over 1,000 factories in Singapore have noise hazards and more than 50,000 workers are exposed to excessive noise at work. Prolonged exposure to excessive noise can cause deafness - a chronic disease that cannot be cured. It may also cause tinnitus (persistent 'ringing' sound in the ears). Selecting the right earplug means more than choosing the one with the highest Noise Reduction Rating (NRR). Comfort is another important factor in the selection. The material, shape and size of earplugs affect the fit. Earplugs are commonly used when comfort and convenience are a must. With our extensive range of hearing protection, there is definitely one that is able to meet your requirements.
