Human beings can be an active part of this world only with the help of the five senses - namely sight, hearing, smell, taste and touch. If one of the senses breaks down, an individual faces great changes with difficult challenges coming on the way.

 

Hearing Loss and Its Causes

Partial or total inability to hear is termed as hearing loss. Various causes like ear infections, malformations in the internal ear structure, overexposure to loud noises, infections or other health conditions, genetic issues and even leading an unhealthy lifestyle might lead to hearing impairment. However, there is always a way out. There are many hearing loss treatment options like advanced and smart digital hearing aids and cochlear implants which are designed to make your life better.

Parts of the Human Ear

The human ear comprises three main parts, namely the outer ear, the middle ear and the inner ear.

  • The outer ear - It consists of the pinna or the auricle and the auditory canal. The tympanic membrane or the eardrum divides the outer ear from the middle ear.

  • The middle ear - The middle ear of mammals consists of three small ear bones, namely malleus, incus, and stapes (hammer, anvil, and stirrup) - together known as the ossicles. The ossicles provide further energy and impetus required to transfer the sound signals from the eardrum to the oval window of the cochlea. The eustachian tube is another part of the middle ear. It connects the middle ear with the back of the nose and helps to equalise the pressure in the middle ear, thus helping in the proper transfer of the sound waves.

  • The inner ear - The inner ear consists of the most important organ responsible for hearing - the spiral-shaped cochlea. Apart from the cochlea, the inner ear also comprises the vestibule and the semicircular canals which are responsible for body balance.

 

How Do We Hear?

The human hearing mechanism is quite a complex one. There are a series of steps involved in between the receipt of the sound waves by the outer ear to our actual act of ‘hearing’ it. Let’s have a brief look at them -

  • The outer ear receives the sound waves which travel down the auditory canal and strike the eardrum.

  • This causes the eardrum or the tympanic membrane to vibrate.

  • These vibrations are then passed over to the ossicles or the three tiny ear bones.

  • The ossicles amplify the sounds and transfer them to the inner ear.

  • The fluid-filled hearing organ - the cochlea receives these sounds and processes and converts them into electrical impulses.

  • These converted sound signals are then transferred to the brain via the auditory nerve.

  • The brain on receiving them translates them as sounds which are then perceived by us. This is the moment when we can actually ‘hear’.

However, apart from hearing, the vestibular system situated in our inner ear is also responsible for body balance and equilibrium. This is why hearing loss is often associated with vertigo and balance problems.

Our ear is, therefore, an important organ of our body. Damage caused to it would bring about many health conditions.

Consult a certified audiologist to get your hearing test done from time to time, to avoid any complications. An untreated hearing loss might have a great impact on one’s life. Treat any hearing problem on time and never delay in getting proper treatment of hearing loss.
