Do you remember when you go to the doctor for a physical and they check your hearing by having you raise your hand if you hear a beep? The doctor tests our signal detection; our ability to detect sounds under different conditions. Doctors test for hearing in kids and teens especially because they are more exposed to loud noises (such as loud music). A study that took place at Harvard says that one in five teens lose part of their hearing due to exposure to loud music. According to the National Institute of Health, the louder the sound, the shorter the time period before loss of hearing can occur (noise-induced hearing loss). However, most cases of hearing loss are due to age; the older you get the harder it gets for you to hear. And hearing loss can be caused by loss of sensory cells or the weakening of the hearing nerve. I have examples of natural hear loss in my own family; my mom and dad are getting older and I find myself repeating myself two or three times before they actually understand what I am trying to say. Another example is just the volume of the TV when I am watching TV compared to the volume when my parents are watching TV. My parents watch TV at a higher volume than I do because they are slowly losing their sensory cells. In conclusion, we really need to be careful about the noises and frequencies we are exposed to because they can cause permanent damage.
Can You Turn Up The Volume?
