Sound is measured in two ways – volume or level (decibels) and pitch or frequency (hertz). The results are then recorded by the audiologist on a graph called an audiogram.
The audiogram is a graphic representation of audiometric data and shows your hearing ability compared to a normal hearing range. Vertical lines on the audiogram show pitch and frequency, the horizontal lines show loudness and intensity.
The zero decibel shown at the top presents a barely audible sound, each line below presents a louder sound. Each test frequency is marked on the softest sound you have responded too.
Levels of hearing loss
Mild – Difficulty in following speech usually in noisy situations.
Moderate – Difficulty in following speech and other quiet sounds, especially in noise situations
Severe – Unable to hear speech even in quiet surroundings.
Profound – almost all sounds are inaudible
The audiologist will discuss the results with you and advise if a solution if required.
