How does hearing loss occur
Every day, we are exposed to sounds in our environment, things like the sounds from television, appliances, work equipment and traffic. Most of the time, we hear these sounds at safe levels that do not affect our hearing and cause a hearing loss. However, when we are exposed to louder harmful noise.
Sounds that are too loud or loud sounds that last a long time, sensitive structures in our inner ear can be damaged. This causes hearing loss. Hearing aids can help to reverse some effects of this type of loss. Hearing aids don't just provide you with hearing but also help to exercise your ears for better natural hearing.
These sensitive structures, called hair cells, are small sensory cells that convert sound energy into electrical signals that travel to the brain. Once damaged, our hair cells cannot grow back. That is why its important to be aware of the damage loud noise can cause when exposed to them. In some extreme cases noise protection can be made use of with custom design hearing aid plugs that filter out certain tones to reduce the effect of loud noises.
In summary loud sounds play a real role in your hearing every day. Hearing aids can help to bring back a lot of your hearing but unfortunately cannot replace the natural hearing god gave us, so prevention is always best look after your ears.
