Why Noise Reduction Headset So Important

In modern times there are so many industries that the staff has to work with high noise, such as construction sites, manufacturing industries, entertainment venues, airports, harbor, shooting ranges. If you know the hazard of the noise, you will know why noise reduction headset so important.

What is the hazard of noise?

When a person is exposed to a noise environment exceeding 85 decibels, it may cause damage to hearing. If the damage is not significant, hearing can be restored after rest. If exposed to high noise for a long time, auditory fatigue cannot be recovered. Over time, auditory receptors in the inner ear will have qualitative lesions, causing permanent hearing loss, that is, noise-induced deafness.

According to the recommendations of the National Institute of Occupational Safety and Health (NIOSH), people working in a noisy environment should wear hearing protection if the noise level is 85 dB or more. Workers exposed to any single impulse noise level exceeding 140 dB should wear dual hearing protection (ie earplugs and earmuffs should be worn at the same time).

Working principle of noise reduction headsets and selections：

The noise reduction headset is divided into two types based on the working principle, passive noise reduction, and active noise reduction.

Passive noise reduction is divided into physical passive noise reduction and electronic passive noise reduction.

The working principle of active noise reduction headphones is to generate a reverse sound wave through the noise reduction system with external noise and merge the noise to achieve the noise reduction effect.

Physical passive noise reduction headphones use external objects to wrap the ears to form a closed space, and mainly use sponges and silicone earplugs materials to block external noise. Our heavy-duty series physical noise reduction headsets are suitable for engineers of manufacturing, technicians of the processing industry, construction teams, airport staff, racing teams, and EHN001 and EHN002 are perfect for hunting, shooting, constructing, woodworking, landscaping work, weeding, mining, and so on.

Electronic passive noise reduction headphones are based on physical passive noise reduction headphones and added the function to pick up ambient sounds, amplify human voices and environmental sounds through smart circuits, reduce impact noise, and achieve the purpose of enhancing hearing protection and hearing.
