Earline headphones and hearing protection

Some jobs require the use of specific equipment. For workers who regularly use certain types of machinery or work in a particularly noisy environment, wearing hearing protection is mandatory. Reducing the sound level protects against the risk of deafness. To work in complete safety and increase productivity, opt for the headphones and noise-canceling plugs offered by Earline.

Presentation of the brand

The Worldwide Euro Protection group was founded in 1953. This major player in the creation of PPE began by offering protective gloves. Particularly ambitious, this French company located in Miribel, in the department of Ain, in the Auvergne-Rhône-Alpes region, has expanded its activities over time. Currently, it is present in more than 70 countries around the world.

The production of individual hearing protectors is entrusted to its subsidiary Earline. The latter has managed to gain notoriety and stay one step ahead of the competition. It was based in particular on the immense know-how that the group has acquired over its 65 years of existence in the field of creating personal protective equipment.

The usefulness of professional hearing protection - Noise protection

In recent years, noise has become increasingly important on construction sites and in workshops. Noise pollution, over prolonged exposures, can cause serious problems such as hearing loss. In addition, the higher the noise level, the greater the risk of workers suffering from hearing loss, with a rapid deterioration in hearing capacity. Physical and mental health is directly affected, as noise pollution can cause stress and impact the endocrine, cardiovascular and immune systems.

It is for this reason that wearing hearing protection is essential in order to maintain good hearing health. When the sound exceeds 80 dB, French law requires employers to provide their employees with individual hearing protectors. These accessories are essential in certain sectors of activity such as the wood or construction industry, or even the weaving trades. Indeed, the machines used have a sound level generally approaching 100 dB.

How to choose your hearing protection equipment?

The choice of noise protection depends on the level of noise pollution in the workplace of the professional, but also on his duration of exposure to this noise.There are different levels of noise: non-painful, tiring, painful and painful

Thus, it is necessary to calculate the minimum sound attenuation adapted to the professional's environment so that the noise level is equivalent to the least dangerous level, i.e. 75 dB. For example, if the noise pollution level of a place is 120 dB, the appropriate protective equipment must attenuate the noise by at least 45 dB.

This choice also depends on the working environment:

• If the professional works in an electrical place, it is best to wear a dielectric helmet (does not conduct electricity).
• If he wants to hear the voice, the alarms… Eliminating dangerous noises, the best is the active headphones.

The different types of hearing protection

The choice of individual hearing protectors must be made according to the type of work and the noise level. To meet the needs of professionals, the Earline brand offers a wide range of protective accessories:

• Ear Plugs:

1. with headband (with spare tips), appreciated for their lightness and the wearing comfort they display
2. classic, reusable and easy to use, able to adapt to the morphology of the ear canals

• Noise-canceling headphones (classic or with FM radio) that fit perfectly to the morphology of the head

All the hearing protectors offered by Earline have a so-called "passive" operation. This means that sounds are blocked before they reach the ear canal. However, surfing on the wave of technological progress, the brand offers so-called “active” operating accessories, intended for particularly noisy environments. These incorporate ANR (Active Noise Reduction) technology, a resolutely efficient signal processing and restitution system.

Standards

Coming into force on February 15, 2006, European Directive 2003/10/EC was put in place to protect workers exposed to noise all day long. Therefore, personal hearing protectors must comply with the following standards:

• EN 352, a European standard broken down into 5 points

• EN 352-1 relating to earmuffs
• EN 352-2 on earplugs
• EN 352-3 related to the headband mounted on hard hat dedicated to industry
• EN 352-4 relating to headband with level-dependent attenuation
• EN 352-8 for the headband incorporating an entertainment radio

• EN 458, a European standard indicating recommended residual level ranges at the ear, with recommendations for the selection, use and maintenance of hearing protection
• En 13819, a European standard indicating the test methods carried out to assess the level of protection of personal hearing protectors.
