kõrvakaitsmed

Kõrvakaitsmed, commonly known as ear defenders or ear muffs, are protective devices worn over the ears to reduce the level of sound that reaches the eardrum. They are designed to attenuate noise, especially in environments with high decibel levels, thereby preventing noise-induced hearing loss. The effectiveness of kõrvakaitsmed is measured by their Noise Reduction Rating (NRR) or Single Number Rating (SNR), which indicates how much sound they can block.

Kõrvakaitsmed typically consist of a headband that holds two earcups in place over the ears. The earcups are lined with sound-absorbing material, creating a seal around the ear to block out external noise. Some models are designed to be worn on the head, while others can be attached to safety helmets. There are also electronic kõrvakaitsmed that amplify quiet sounds while still protecting against loud noises, making them useful for hunters or industrial workers who need to communicate or detect important sounds in noisy environments.

These devices are widely used in various settings. In construction, manufacturing plants, and airports, workers are exposed to continuous loud noises and require kõrvakaitsmed to protect their hearing. They are also used by musicians, motorsport enthusiasts, and individuals at shooting ranges. Even for everyday activities like lawn mowing or attending loud concerts, kõrvakaitsmed can provide valuable hearing protection. Proper fit and maintenance are crucial for ensuring the maximum effectiveness of kõrvakaitsmed.
