The outer ear a€“ which is the part of the ear you see a€“ funnels sound waves into the ear canal.
The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. The auditory nerve carries the electrical signals from the inner ear to the brain, which interprets the signals as sound that you recognize and understand. You might notice after leaving a very loud event such as a concert or football game that you dona€™t hear as well as before.
If you think you are having any difficulty with your hearing, you should visit your doctor or healthcare professional as soon as possible.
Hearing loss can happen when any part of the ear or the nerves that carry sounds do not work in the usual way.
Noise-induced hearing loss can result from a one-time exposure to a very loud sound or blast or from listening to loud sounds over and over. However, one type of hearing loss that can be prevented is noise-induced hearing loss, which occurs when your ears are exposed to prolonged loud noise. To make that happen, the many parts of the ear must change the vibrations into signals to the brain.


As the waves peak, they cause tiny hair cells (types of receptors that can detect sound and head motion) to bend, which converts the vibrations into electrical signals.
Up to 30%a€“50% of those hair cells can be damaged or destroyed before changes in pure tone thresholds (one measure of hearing loss) occurs. It is important to look after your ears and to make sure that you protect your hearing in all noisy places, both at work and at leisure.Ears are very delicate and complex. However, it can become permanent when parts of the ear needed for hearing are damaged beyond repair or die. Listening to noise for a long time can overwork the hair cells, which can lead to cell death. By the time hearing loss is detected, many hair cells already have been destroyed and cannot be repaired. This is because the hair cells similar to blades of grass, will bend more if the sound is louder, but they will come back straight after some recovery period. The inner ear contains thousands of tiny cells that process sounds and pass information on to your brain.
Repeated exposures to loud noises will eventually destroy many hair cells,  and thus can gradually reduce your ability to understand speech in noisy environments.


Tinnitus is the word for noises that some people hear in the ears or in the head - buzzing, ringing, whistling, hissing and other sounds.
Early damage may not show up on your hearing test, but can create a a€?hidden hearing lossa€™ which may make it difficult for you to understand speech in noisy environments. You may also become unusually sensitive to sound, which can be distressing and uncomfortable.The louder the noise is and the longer you are exposed to it, the greater the risk of damage to your hearing.
The cumulative effect of noise affects how well you might hear later in life, and how quickly you might develop hearing problems, even after exposure has stopped.
If you have to be in a very noisy situation, always protect your ears with ear protectors a€“ earplugs or earmuffs a€“ and get away from the noise as quickly or as often as you can.Remember that listening to loud music for long periods of time can also damage your hearing.
