Hearing Loss From Noise

The eardrum is like a speaker in lamens terms. It moves back and forth when the incoming sound waves are pushed through. Just like a speaker, if the incoming wave is too big, the membrane of the ear (or speaker) is pushed too far and tears away.

Noises are everywhere and it is very unlikely we can escape. However, loud noises are a different story. These are little bit easier to escape. When we are exposed to harmful noise—sounds that are too loud or loud sounds that last a long time—sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss (NIHL).Loud noises such as big tractors, rock concerts etc... Hair cells in our ear are small sensory cells that convert sound energy into electrical signals that travel to the brain. Once damaged, our hair cells cannot grow back. Lifestyle changes can help reduce hearing loss.

So you're saying that constant exposure to loud music in concerts or other loud sounds will damage our ear drum?

Does anyone know if a mp4 or similar to that effect will cause permanant damage to our ears?

Yes it does cause damage. Anything loud for a substantial amount of time will cause some sort of damage. Some severe, some mild. It is simple to know when loud is too loud.

Hearing aids reduce background noise.

When exposed to loud sounds for a longer period of time than usual, these people might experience headaches. This could be a symptom that the ear drums are already suffering and might be a sign for further damage that could possibly result into something more severe!

When you hear something loud constantly, your eardrums suffer and can be damaged long term. Allowing yourself to hear loud noise this often is harmful to your hearing. We already lose our hearing as we age, we do not want to further increase our risk for more severe hearing loss.

When loud sounds are exposed to the ear for a short time, one may experience what's called a temporary threshold shift, or a temporary hearing loss. This hearing loss may be accompanied by tinnitus (a ringing in the ears). One may recover from the temporary loss. But if the ear is exposed to loud sounds over longer periods of time, the hair cells can be permanently damaged, causing permanent sensor neural hearing loss.
