What is hearing loss?
... 1. Conductive Hearing Loss: A conductive hearing loss means something is wrong with the outer ear or the middle ear. Some people are born without the pinna (the part of the outer ear that we can see) to catch sound. Others have a blockage of wax in their ear canal or fluid behind their eardrum. 2. S ...

Exposure to sounds that are loud enough or occur long enough can damage the ears’ cilia so that they can no longer bounce back into shape and can no longer send sound to the brain. This is the cause of noise-induced hearing loss (NIHL). ...
