Hearing Loss
You can loose your hearing just by living, if you ride a boat, play music, shoot guns for hobby, anything!
You can get hearing loss also by trauma or it being hereditary. Either way the statistic is though people who feel they have hearing loss do not get help until approx fifteen years later. In reality you hear with your ran as well you should get help right away because the longer you wait the longer id it to re train your brain how to hear and believe it or not there is a moment where it is to late to get help and your brain can no longer rehabilitate it self
