    Hearing Protector Device Selection – Part 1.


    In this episode host Mark Reggers speaks with guest Luciana Macedo, Occupational Hygienist for 3M Australia/New Zealand in the Personal Safety Division to help you work through the range of hearing protection options available to select the most appropriate for a wide range of noise levels.  

    It’s a loud world out there, and some of us work in hazardous noise environments. Being around too much loud noise can make you lose your hearing. Don’t put your hearing at risk, once it’s gone, you can’t get it back. Repeated exposure to loud sounds, greater than 85 dBA, can cause permanent hearing loss and tinnitus, as well as other negative health effects that can impact your well being, such as: stress, anxiety, hypertension, sleep disturbance and fatigue. Here’s the good news, there’s a lot you can do to protect your hearing with the appropriate hearing protection.
