Noise can cause physiological\u00a0changes, including cardiovascular, hormonal and metabolic\u00a0problems.\u00a0Over a long period of time these changes can affect health\u00a0and lead to cardiac problems, hypertension, fatigue, digestive problems,\u00a0troublesome tinnitus\u00a0and, of course, permanent hearing impairment.\u00a0It goes without saying that good protection from harmful noise exposure\u00a0is necessary to reduce the negative impact of noise on health\u00a0and hearing.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>How hearing protectors work?<\/strong><\/h2>\n<p>Traditional hearing protection (earplugs or\u00a0shells) act as a barrier to sounds. The sound arrives at the inner ear with\u00a0less strength and a decreased level of decibels.<\/p>\n<p>For custom fitted noise protectors, there are two types available:\u00a0filtered and non-filtered. Non-filtered protectors offer\u00a0an excellent protection against noise, but make communicating more difficult. If you want, you may ad filters to your protectors :\u00a0they allow some conversation to go through thus enhancing communication. The noise abatement can be adjusted to your needs.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Wearing hearing protectors correctly<\/strong><\/h2>\n<p>You might think that the way you wear earplugs or shells has little\u00a0influence\u00a0on their level of protection. But you would be wrong! It has\u00a0been shown that wearing these hearing protectors correctly has an\u00a0enormous\u00a0impact on their effectiveness. In fact, earplugs or shells\u00a0that do not fit well allow sounds to enter through small spaces, even if\u00a0they are tiny. Despite using a barrier, sound can take other routes, for\u00a0example\u00a0through:<\/p>\n<ul>\n<li>the skull bones<\/li>\n<li>vibrations<\/li>\n<li>the protector itself (depending on the material used\u00a0to make the protector)<\/li>\n<li>small spaces between the protector and the ear (if not well fitted,\u00a0the hearing protector can lose 5 to 15 decibels of effectiveness)<\/li>\n<\/ul>\n<p>It should also be noted that removing your hearing protection, even for\u00a0a short time, can affect hearing. Using them all the time is essential. For\u00a0example, if a worker removes his or her protectors for one minute during\u00a0eight hours of work, 25% of the protectors\u2019 effectiveness is lost.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Effects of noise exposure on hearing<\/strong><\/h2>\n<p>According to the World Health Organization, exposure for eight hours a\u00a0day to a sound level above 75 dBA can be dangerous. Quebec\u2019s <i>Regulation\u00a0<\/i><i>respecting occupational health and safety <\/i>is much more permissive\u00a0(90 dBA\/8 hours). Unfortunately, even when this regulation is followed,\u00a0it does not guarantee that our ears are safe.<\/p>\n<p>The most effective method is to reduce noise at its source, by building\u00a0and buying quieter machinery and equipment and by limiting exposure\u00a0time to harmful noise. Keep in mind that hearing protection is still\u00a0recommended for noise exposure, whether the strategies mentioned\u00a0here are applied or not.<\/p>\n<p>&nbsp;<\/p>\n<p>For more details about the different hearing protectors, <a href=\"http:\/\/legroupeforget.stage.okam.io\/en\/make-an-appointment\/\">make an appointment with an audioprosthetist today!<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Preventing the harmful effects of noise, such as wearing hearing protectors,\u00a0is becoming more\u00a0widespread,\u00a0and for good reason!
