Hereof, how do ear protectors work?Ear defenders protect the wearer from extreme noises. The head-band and outer covering is usually made from a hard thermoplastic or metal. The protection usually comes from acoustic foam – this absorbs sound waves by increasing air resistance, thus reducing the amplitude of the waves.Likewise, how does noise reduction rating work? Noise Reduction Rating (NRR) is a unit of measurement used to determine the effectiveness of hearing protection devices to decrease sound exposure within a given working environment. The higher the NRR number associated with a hearing protector, the greater the potential for noise reduction. Thereof, when should you wear ear protection? People should wear a hearing protector if the noise or sound level at the workplace exceeds 85 decibels (A-weighted) or dBA. Hearing protectors reduce the noise exposure level and the risk of hearing loss. If hearing protection is required, then a complete hearing conservation program should be implemented.Are earmuffs better than earplugs?Because they fit directly into the ear canal, ear plugs offer greater protection than ear muffs. Ear muffs, however, are more difficult to carry and protect, making them more cumbersome for workers. If you need to wear other types of PPE, then ear plugs are probably the best choice.
