Hearing Protection Devices: Often Used To Prevent Noise-Induced Hearing Loss (NIHL)

 

Hearing Protection Devices

Hearing protection devices, such as earmuffs, ear plugs, hearing bands, and uniform attenuation earplugs, are medical devices that are worn in or over the ear when exposed to hazardous noise to help prevent noise-induced hearing loss. These devices also help protect against other effects of noise exposure such as hyperacusis and tinnitus. Different types of hearing protection are available in the market that people can wear to help reduce the impact of noisy environment and risk of developing noise-induced hearing loss. Hearing protection is an essential part of preventing hearing loss. These devices fit inside or over the ear canal to block sound waves from entering the innermost parts of the ear.

Hearing Protection Devices are extensively used to prevent noise-induced hearing loss (NIHL). NIHL occurs when the sensitive structures in the inner ear are damaged by loud sound, which may lead to a permanent hearing loss. It can occur in both ears or in one and can be temporary or permanent. In simple terms, NIHL is permanent damage to the tiny hair cells of ears. Hearing protection devices assist in preventing sudden noise-induced hearing impairment. These devices are not only designed for people who work in industries, but also for people who frequently interact with loud noises. Hearing protection devices are protective gears that can effectively lessen the effects of hearing loss caused by exposure to loud noise.

These protective devices are available in different forms and styles that are intended to fit any ear type. Electronic hearing protection devices are designed to minimize or negate undesirable noise. Non-electronic hearing protection devices, on the other hand, are those that use structural and mechanical parts to minimize or negate noise-induced hearing loss. These types of devices do not need electricity to work, and some of them are completely wireless. However, in order for these devices to have any worthwhile effect on people’s hearing impairment, they must be worn for an extended period of time, several hours every day. Many people assume that hearing aids just make sounds louder, but some hearing aids also reduce background noise.

There are many kinds of hearing protection devices in the market. Earmuffs are the smallest among all devices, while ear plugs are typically used to protect ears from loud noises, foreign objects, water, dust, etc. Ear Muffs are very easy to fit, but they normally offer less protection than ear plugs. This is because they only sit over the ears, rather than directly in the ear canal. Ear muffs and earplugs are the most commonly used hearing protection devices, an incredibly effective way to prevent premature hearing damage. Earplugs are useful for protecting ears against loud noises, but many people use them to sleep. They can make a world of difference for light sleepers or people who live in a noisy area.

Hearing protection devices reduce the noise exposure level and the risk of hearing loss when worn correctly. National Institute for Occupational Safety and Health (NIOSH) recommends that workers shall be required to wear hearing protectors when engaged in work that exposes them to noise that equals or exceeds 85 dBA as an 8-hour TWA. Thus, there is an increasing demand for hearing protection devices worldwide.
