Hearing | How We Hear | Hearing Hub Audiologists

Hearing | How We Hear | Hearing Hub Audiologists

Hearing is a sense we should not take for granted. By understanding how the  complex sense of hearing occurs, I hope to make you cherish your hearing (if you don’t already). This would also be able to help you identify if you  or your child has any hearing-related conditions (hearing impairments such as hearing loss, tinnitus) which require help.

Because hearing is a complex sense, it is best explained with the aid of a picture of the anatomy of the ear.

Hearing is a complex sense we should care for and cherish.
Hearing is a complex sense which we should all care for and cherish.

The human ear is made up of three parts, namely the Outer Ear, Middle Ear and Inner Ear. Each of these parts play an important role to allow you to hear.

The Outer Ear

This is the part we usually associate with hearing. The Outer Ear is mainly made up of the Auricular Lobule or Earlobe. The Earlobe collects and chanels sound into the Concha or External Ear Canal. The Ear Canal amplifies or boosts the sound waves thereby funneling them toward the Eardrum (Tympanic Membrane).

The Middle Ear

During this part of the hearing process the above mentioned sound waves in turn cause the eardrum to vibrate via the Ear Canal (External Acoustic Meatus). Three small bones (Ossicles), namely the Hammer (Malleus), the Anvil (Incus) and the Stirrup (Stapes)  are also situated in the Middle Ear. These bones alsp vibrate thereby magnifying the eardrum’s vibrations, which in turn are transferred to the Inner Ear.

The Inner Ear

This is the final stage in the hearing process. The Inner Ear is made up of the Cochlea and various nerves which go to the brain. The Cochlea is the sensory organ which is responsible for transmitting tiny electrical charges via the Cochlear nerve to the brain. The Cochlear does this through the stimulation of thousands of sensory hair cells which are contained in fluid filled chambers. Finally the brain interprets these electric charges or pulses as the sense of hearing or the so-called sounds we hear.

Hearing Aid Users | How To Improve Your Listening Skills

How to Improve Your Listening Skills when using Hearing Aids.

You or your child should maximize your respective listening skills, especially if you use hearing aids.

To get the most out of your hearing aids you should practice a few techniques with regard to improving you listening skills.

If you are in an environment where a few different sounds can be heard in your vicinity, practice shifting your concentration to each sound individually.

When you first start wearing hearing aids, make a point of “blocking out” or ignoring the sounds that you don’t find are important.

Focus your attention on the sounds which you find important.

As always, be patient with yourself.

If you have any questions regarding the above topic, hearing aids or hearing impairments; feel free to contact me for more information and a free initial consultation.

Types of Hearing Tests for Children Who May Have a Hearing Impairment

Hearing Testing for Children with hearing loss

There are a few tests which I perform to effectively treat your child’s possible hearing loss.

Types of Hearing Tests for Children Who May Have a Hearing Impairment

I perform various Hearing Tests to find the best audiological solution for your child who may or may not have a hearing Impairment and if so, how best to treat it.

Behavioural Hearing Tests: These tests are designed to get a response from your child through their hand gestures, pictures, games and/or verbally.

There are various ways through my specialised audiological equipment that I use for newborns or babies who can’t  respond reliably to Behavioural Testing. There are three tests which can be performed:  a small loudspeaker is used together with a microphone (Otoacoustic Emissions), click sounds are played through ear phones (Auditory Brainstem Response) and finally with a specialised instrument which blows a gentle puff of air into the ear (Acoustic Immittance testing / Tympanometry).

For more information or to setup a consultation please don’t hesitate to give me a call.

Causes of Hearing Loss in Children

Hearing loss for children requiring Hearing Aids, in Pretoria.

Hearing loss for children.


Causes of Hearing Loss in Children


Children can suffer from two kinds of hearing loss, namely  Sensorineural and Conductive hearing loss.

With sensorineural hearing loss, it is either sensory (cochlea part of the ear) or the auditory pathways to the brain (neural) are not working properly. This kind of hearing loss is treatable but permanent. It can be treated by hearing aids / hearing instruments or possibly cochlea implants.

With Conductive hearing loss, the middle and outer ear are affected by something (earwax, swimmer’s ear, foreign objects or a middle ear infection). They are all medically treatable.


Signs of Hearing Loss in children which possibly require Hearing Aids | Pediatric Audiologist in Pretoria.

Hearing Aids for children at Hearing Hub Audiologists in Pretoria

Your child can live a full life with a hearing impairment.

I specialise in Pediatric Audiology and I would like to share some helpful information with you.

As parents, you should always try to be aware if your child doesn’t respond appropriately to sounds.

This can be because your child may not be paying attention to the sound but you should continually assess the situation if you notice the following signs:

1) If your child doesn’t react to very loud  or high-pitched sounds.

2) If your child doesn’t respond to voices on the phone or switches ears during calls.

3) If your child sits too close to the TV when the TV’s volume is adequate for the other     people watching.

4) If your child watches the faces of people who are speaking to him / her very closely.

5) If your child says: “huh?” or “what?” often.

6) If your child is surprised when his / her name is called out at a slightly loud or even normal level.

7) If your child is not aware of some who is talking to him / her, especially when there are minimal distractions.

Please feel free to get in touch with me if you have any questions or if your child suffers from the above factors.
