When it comes to ear plugs, they are rated based on their ability to reduce noise, which is measured by the Noise Reduction Rating (NRR). The NRR indicates how much noise the ear plugs can block out, measured in decibels (dB). The higher the NRR, the more effective the ear plugs are at reducing noise. For example, ear plugs with an NRR of 33 dB provide very high noise reduction. In Europe, the Single Number Rating (SNR) is commonly used, which also measures noise reduction in decibels but is calculated differently. These ratings help you choose the right ear plugs for your needs, whether for sleeping, working in noisy environments, or attending loud events.
