Noise induced hearing loss (NIHL) is a common yet preventable condition that affects millions of people worldwide. This type of hearing loss is caused by exposure to loud sounds, which can damage the delicate structures in the inner ear. In this blog post, we will explore the causes, symptoms, prevention, and treatment of noise induced hearing loss. We will also discuss who is at risk and how to protect your hearing.
Understanding Noise Induced Hearing Loss
Noise induced hearing loss occurs when the tiny hair cells in the cochlea, a part of the inner ear, are damaged by loud noise. These hair cells are responsible for converting sound vibrations into electrical signals that the brain interprets as sound. Once these cells are damaged, they cannot regenerate, leading to permanent hearing loss.
