Pure tone audiometry (PTA) is a very important hearing test. It is used to identify hearing threshold levels of an individual. It is a test which enables the determination of the degree, type and configuration of hearing loss. It is therefore a key hearing test which provides the basis for diagnosis and management of the loss of hearing. PTA is a subjective, behavioural measurement of hearing threshold. One reason for this is because; through the test patient response to pure tone stimuli determines its effectiveness. Therefore, PTA is used mostly on adults. Children who are not old enough may be unable to fully cooperate with the test procedure.
Pure Tone Audiometry: the procedure involved
Pure-tone thresholds (PTTs) indicate the softest sound audible to an individual at least 50% of the time. Hearing sensitivity is plotted on an audiogram. This is a graph displaying intensity as a function of frequency. The PTA is a very important hearing test. It is considered as the gold standard for the assessment of hearing loss. Hearing impairment is defined by the World Health Organization (WHO) as a hearing loss with threshold limits higher than 25db in one or both ears. As per WHO the degree of hearing loss can be as classified as mild, moderate, severe or profound. The results derived from the PTA test are therefore a good indicator of a person’s level of impairment. It determines the ways and means as to how the hearing loss is to be treated.
