What is hearing?
A person who is unable to hear as well as someone with normal hearing – hearing thresholds of 25 dB or better in both ears – is said to have hearing loss. Hearing loss may be mild, moderate, severe, or profound. It can affect one ear or both ears, and leads to difficulty in hearing conversational speech or loud sounds.
- A grandchild’s first word, rustle of leaves in the wind, the clinking of glasses at the table or whispered secrets from your best friend. These are the moments we hold dear. It’s these sensory experiences that enrich our lives.
- Hearing enables us to understand other persons and help to interact with the world around us.
- Good hearing is so important in our day-to-day lives, yet most people with normal hearing don’t even think about what it means to be able to hear well.

How does our ear work?
Need to understand how and why hearing loss happens, it helps to understand how the ear works.
- Firstly, I would like to call it the miracle of nature.
- The ear is an amazing and incredibly skilled organ that performs the wonderful and highly complex task of hearing.
The ear is made up of three different sections: the outer ear, the middle ear, and the inner ear. These parts work together so you can hear and process sounds.
Outer Ear– The outer ear picks up sound and transmits it to the eardrum via the ear canal.
Middle Ear– The sound makes the eardrum vibrate and is amplified by the three tiny bones of the ears.
Inner Ear– The cochlear converts movements of these 3 tiny bones into electrical signals. The auditory nerve transmits the signal to the brain.
What is hearing loss?
Hearing loss happens when there is a problem with one or more parts of the ear or ears, the nerves coming from the ears, or the part of the brain that controls hearing. “Impairment” means something is not working correctly or as well as it should.

Most likely, people with hearing impairment need clarity, not
- Hearing impairments can occur in all parts of the ear, dysfunctions of the outer or middle ear can generally be treated with medication or surgery.
- However, a good 80 percent of all hearing impairments are caused by dysfunctions of or damage to the inner ear.

What are the signs of hearing impairment?
- Hearing loss generally develops slowly over many years, the effects become apparent only gradually.

- Relatives, friends or colleagues are often the first to realize that something is wrong.
- However, there are clear signs that your hearing is not entirely as it should be.
- Perhaps you find it difficult to understand the phone conversation clearly?
- Does your family complain about the volume when you are listening to the radio or television?
- Do you find it difficult to follow a conversation in a restaurant or when there is a lot of noise in the street around you?
- Do you often feel exhausted after family celebrations because listening is such an effort?
