There are many measures of an individual's hearing. However, the most common hearing test is known as the pure tone audiogram. The aim of the audiogram is to provide you with a baseline profile of your hearing ability

The pure tone audiogram is a measure of hearing sensitivity. The aim is to find the 'hearing threshold' - the quietest, audible sound an individual can perceive.

The sounds are presented to each ear individually via headphones or inserts earphones. A headband will also be placed behind your ear to measure bone conduction. During the process you will be asked to push a button when you hear the different sounds.

Your hearing sensitivity is plotted on a graph called an audiogram. The graph displays the intensity of the sounds on the vertical axis as decibel hearing level and frequency in hertz on the horizontal axis.

Either ourselves or your Ear Nose and Throat Consultants will discuss the information plotted on your audiogram with you. We can determine any effects on your hearing sensitivity and then decide together on any appropriate course of action.

In addition to this we also routinely use discrimination tests - The Speech Audiogram.   These are a measure of ones ability to discriminate words or sentences - in quiet or in the presence of background noise.  We use these particularly for hearing aid assessments/outcome measures but occasionally for diagnostic purposes also.  We believe it is absolutely imperative to use discrimination tests when fitting hearing aids - in order to counsel correctly on the likely success of any hearing aid prescription.
