How does the ear work?

The anatomy of the ear, and hearing care

Understand your hearing

When your hearing is working normally, information is being passed through each section of the ear to your brain. Your brain receives these messages and you will naturally respond.

The ear is the organ responsible for hearing and balance. Thanks to its mechanism it makes us receive the sound waves transforming them into proper sounds, making sense to us.

Anatomy of your ear

There are three parts of the ear anatomy, the outer ear, the middle ear and the inner ear. The inner ear is also called the cochlea.

The outer ear

The beginning of the journey

Sound travels in waves travel through a narrow passageway called the ear canal to the ear drum. The outer ear (pinna) ‘catch’ sound waves and direct them through the ear canal to the protected middle ear. These incoming sound waves cause the ear drum to vibrate. This is where the process of understanding these sound waves begins.

The middle ear

The encounter with the eardrum

Through these vibrations, imagine the skin on a musical drum vibrating when you strike it, causes the ossicles, a tiny chain of bones (malleus, incus, stapes) move in the middle ear.

The middle ear is connected to the back of the nose and throat by the Eustachian tube. This means that when your loved one yawns or swallows, the Eustachian tube can open to equalise the pressure on both sides the eardrum and prevent the membrane from being damaged.  

When you get some cold/flu symptoms the Eustachian tube can become blocked with mucus which can cause a build-up of pressure and temporary hearing impairment or loss as a result.

The inner ear

The true hearing organ

The last  bone in this process ‘taps on the membrane window of the spiral-shaped cochlea, which encourages the fluids in the cochlea to move and in doing so stimulate tiny hair cells on the inner wall of the cochlea. There are over 15,000 of these hairs and stimulating them to move triggers electrical nerve impulses that are taken to the brain via the auditory nerve. From here, it's up to their brain to decipher those impulses as recognisable sounds.

The brain

The destination

It is only here, in the brain, that sounds already transformed into electrical impulses are translated into various perceptions and sensations and become sounds, words, concepts, and emotions.

Ear wax and protection

Everyone has earwax and it can be common to have a build up making it hard to hear properly. Although this can be easily removed, it can happen time and time again, causing hearing loss or affecting the performance of existing hearing aids.

Check how to clean your ears

Taking good care of our ears is crucial as they are an essential and delicate component of our anatomy. To ensure their well-being, it's essential to be mindful of some dos and don'ts while cleaning them.
