Frequently Asked Questions About Hearing

The outer part of the ear (called the pinna) directs sound waves travelling in the air into the ear canal. Higher pitch sounds are enhanced by the shape of the ear canal as they reach the ear drum. Sound is transformed into a slight vibration of the ear drum.

The eardrum is attached to a chain of three hearing bones (the ossicles) that act as a lever enhancing sounds while transferring the signal through the middle ear to the inner ear. The last of these middle ear bones (the stapes), is attached to the oval window, a thin tissue covering and entry point to the fluid-filled inner ear known as the cochlea.

The cochlea is a snail-shaped tube within the skull that contains sensory hearing cells. These sensory cells are situated on a flexible membrane tissue – the basilar membrane. When the oval window vibrates it moves the fluid in the cochlea which in turn moves the basilar membrane and sensory hearing cells are displaced.

Two of the important sensory hearing cells are the outer hair cells and the inner hair cells.
As the hairs move, nerve cells at their base change this motion into electrical signals that are passed along the auditory nerve to the auditory centres of the brain, where the signals are interpreted as recognizable sound.

Today’s hearing aids are available in many different styles, shapes, sizes and colours with various technological features. Many factors are involved in determining the ones that are best for you, including the degree and configuration of hearing loss as well as your hearing needs and life style.

All hearing aids are composed with a microphone, an amplifier, a processor, a receiver, a battery and an earmold. They are designed to enhance your daily life and improve communication without hindering your lifestyle with the goal of assisting you hear in both noisy and quiet environments.

Hearing aids cannot solve every communication problem or restore normal hearing. However, with proper support and education, hearing aids can make a big difference in peoples lives.
