Helping you to hear better
Our ears have a very important job – they help us hear all kinds of sounds around us! But sometimes people have trouble hearing. There are various reasons why someone might have difficulty hearing, and a variety of tools are used to test the health of people’s ears and their ability to hear a range of sounds.
Types of hearing loss
Human ears are complex and are responsible not just for hearing sounds but also for our balance. The cause of hearing loss can be varied as can the level of impact. Finding out the cause helps ensure the correct treatment.
Sensorineural hearing loss
The inner ear is responsible for sending signals to the brain that help you hear different sounds. Sometimes, the tiny hair cells inside the inner ear can get damaged or stop working properly. When this happens, it can make it hard to hear certain sounds or understand what people are saying.
Sensorineural hearing loss can be caused by a variety of things such as loud noises, infections or genetics. Some people are born with sensorineural hearing loss, while others develop it later in life.
There are different treatments available for sensorineural hearing loss such as hearing aids or cochlear implants. These devices can help amplify sounds and make it easier for people with hearing loss to hear and understand what is being said.
Conductive hearing loss
The outer ear is the part of the ear that you can see, while the middle ear is the part that is behind the eardrum. Sometimes, there can be a problem with the ear canal, eardrum or tiny bones in the middle ear that can make it hard for sounds to travel through to the inner ear.
Conductive hearing loss can be caused by things like ear infections, wax build-up or a problem with the eardrum or bones in the middle ear. Sometimes, conductive hearing loss can be temporary and go away on its own. Sometimes, it may require medical treatment.
Treatment for conductive hearing loss may include medication, surgery or hearing aids. Sometimes, simply removing earwax can help improve hearing.
Hearing tests
It’s important to note that hearing aids may not work for everyone and not all types of hearing loss can be treated with hearing aids. If you or someone you know is having trouble hearing, talk to a doctor or audiologist to see if a hearing aid or other treatment option might be helpful. There are a range of different tests used to help accurately diagnose hearing loss.
An audiogram test
To do the audiogram test, you will sit in a quiet room and wear a pair of headphones. The doctor will play different sounds, like beeps or tones, through the headphones at different volumes and frequencies.
When you hear a sound, you will raise your hand or press a button to let the doctor know. The doctor will then mark down which sounds you were able to hear and which ones you couldn’t hear.
The audiogram test creates a special graph that shows how well you can hear different frequencies or pitches of sounds. The graph looks like a line with different points on it.
If you have trouble hearing certain sounds, the audiogram can help the doctor figure out what might be causing the problem and what can be done to help you to hear better.
The audiogram test is an important tool that doctors use to check how well you can hear and to help keep your ears healthy.
Tools to help with hearing
Hearing difficulties can occur for many different reasons – a hearing aid or cochlear implant can help some people.
Hearing aids
Hearing aids have three main parts – a microphone, an amplifier and a speaker. The microphone picks up sounds from the environment around the person wearing the hearing aid and converts those sounds into electrical signals. The amplifier then takes those signals and makes them louder so the person can hear them more easily. Finally, the speaker sends the amplified sound into the person’s ear so they can hear it.
Hearing aids come in different shapes and sizes and can be worn inside the ear or behind the ear. Some hearing aids are also equipped with special features like noise cancellation, which can help make it easier to hear in noisy environments.
Cochlear implants
A cochlear implant is a special device that is placed inside a person’s ear to help them hear better. It works by using small electrical signals to stimulate the nerves inside the ear, which then send signals to the brain that the person can hear as sound.
The cochlear implant has two main parts – an external part that sits behind the ear and an internal part that is surgically implanted inside the ear. The external part has a microphone that picks up sounds, which are then processed by a special computer and sent to the internal part through a small wire. The internal part then sends the electrical signals to the nerves in the ear to help the person hear.
Cochlear implants are very helpful for people who have severe hearing loss and cannot hear well with regular hearing aids. They can allow people to hear sounds they may not have been able to hear before, like music or people’s voices. However not everyone is a good candidate for a cochlear implant – it is important to talk to a doctor or audiologist to see if it’s the right option for you.
Take care of your ears
It is very important to take care of your ears and get regular check-ups to make sure that your ears are healthy and working properly. If you notice that you are having trouble hearing, arrange to see a medical expert so that you can get the help you need!
