Hearing tests measure what sounds a person can and cannot hear. Testing is performed by a trained operator in a quiet test room or sound booth that has been assessed and certified as suitable for testing. At Sonic HealthPlus we test hearing with calibrated audiometers presenting pure tone sounds through a set of headphones.
The simplest test of hearing ability is called Pure Tone Audiometry where the worker listens to a range of beep tones presented in varying degrees of loudness and pitch (frequency) and then responds by pressing a response button whenever they hear the sound. The loudness (decibels) of each tone is reduced until the worker can just hear the sound. The softest sound a person can hear is their hearing threshold for a particular frequency of sound. Both left and right ears are tested individually for a range of frequencies as per the steps determined in the Sonic HealthPlus audiometry procedure, by AS1269:4.2014 or relevant regulatory body where applicable.
