Have you ever gotten in the car in the morning and wondered why you were listing to the music so loudly the day before? Have you ever had trouble hearing or expereienced ringing in your ears after going to a concert or listening to your iPod for a long period of time?
What you are experiencing is damage to your hearing, potentially leading to noise-induced hearing loss and tinnitus (ringing in the ears). Ever short term exposure to very loud noises, such as those you might experience at a shooting range if you were not wearing hearing protection, can cause permanent hearing loss.
But how do you know if you need to put in a pair of ear plugs before you head out to mow the lawn, or if you need to turn the volume on your iPod to the left? The Georgia Local Section of the American Industrial Hygiene Association (GLS-AIHA) wanted to help prevent hearing loss and promote healthy hearing. GLS-AIHA partnered with the Georgia Youth Alliance and the Georgia Tech Research Institute to create “GeRTI,” a mannequin outfitted with a sound level meter. Based on the Dangerous Decibels mannequin Jolene, GeRTI has the ability to show individuals just how loud they are listening to their iPod or other MP3 player when the ear bud from their MP3 player is inserted into GeRTI’s ear.
GeRTI’s début was at the 2010 Construction Education Foundation of Georgia Career EXPO and State SkillsUSA competition in March 2010. Students passing through the World of Safety and Health had the opportunity to stick their ear buds in GeRTI’s ear to see just how loud they were listening to music and they listened to GLS-AIHA volunteers explain the significance of noise-induced hearing loss and tinnitus. Levels were often above 90 decibels and even frequently exceeded 115 dBA.
Since then, “GeRTI” has traveled around the state of Georgia visiting high schools to educate individuals about the importance of healthy hearing. The best part is, we have volunteers who would be happy to escort GeRTI to your school or event to help spread the word.
