PTA (‘Pure-tone audiometry’) is the key hearing test to identify hearing threshold levels of an individual, enabling determination of the degree, type (conductive or sensorineural) and configuration of a hearing loss. PTA is a subjective, behavioural measurement of hearing threshold, as it relies on patient response. Therefore, PTA is used on adults and children old enough to cooperate with the test procedure.
Usually, PTA is performed by using an audiometer in the form of a tabletop unit. Sentiero provides audiometer facilities in the form of a handheld device meeting all demands of a basic diagnostic audiometer of class 3 according to DIN IEC 60645-1.
