Many are unaware about the importance of hearing protection. The world's largest occupational health problem by the World Health Organization is noise in the workplace. Studies by Defense Research and Development Canada indicate that noise induced hearing loss (NIHL) is clearly evident after three to five years of continued or repeated exposures to levels in excess of 85 dBA. NIHL is 100 percent preventable but once acquired, it's permanent and irreversible!
As it has to be worn for a number of hours, the earmuffs that you decide to purchase should be comfortable to wear. It is therefore important to educate workers on the need to wear HPDs and the hazards of exposing themselves to high noise levels. All hearing protection devices are required to carry a Noise Reduction Rating, or NNR rating, that tells you about its effectiveness. For instance, a rating of NNR 10 will reduce the volume of sounds entering the ear by approximately 10 dB.
Electronic hearing protection products are intended to improve short range communications in noisy environments. They are definitely worth considering for protecting your hearing. Electronic ear muffs are simply the best solution to the hearing protection needs of a user in the aviation industry, shooting, hunting or any other industrial applications. Electronic shooting ear muffs provide the ability to hear sounds occurring around you better while wearing the ear muffs than you can without any protection. With the ear muffs in place, your hearing is enhanced through a built-in amplifier.
It is best to opt for a superior technology that allows the user to hear every sound, including conversation, even during high volume noise spikes, instead of the traditional hearing protection devices, which simply block out all sound. Rather than eliminate background noise, it must suppresses it down to a safe 82 decibels below the legislated maximum level of 85 decibels so the user is still aware of their working environment. Most importantly, it must allow face-to-face conversation, mobile phone and two-way radio. Many manufacturers produce HPDs that incorporate protection along with communications capabilities. With these devices allow users to communicate face to face at short and long distances via a two way radio, Bluetooth cell phone or hands free communication with VOX activation in high noise environments.
Hearing protection is vital in high noise environments, but to work it must be robustly supported by management. The right electronic earmuffs can achieve the perfect balance between comfort, noise attenuation and purity of sound.
