Auditory processing disorder: auditory perception beyond classical audiological testing

Vasiliki (Vivian) Iliadou, Christos Sidiras, Ioannis Nimatoudis


Human auditory perception is accomplished with hearing, which is an ability and listening, which is a skill. Pure tone threshold evaluation is the most common test of hearing used in the clinical setting by audiologists. This test focuses on hearing sensitivity in simple sounds (pure tones) and may prove insufficient in identifying listening difficulties in everyday situations. Normal pure tone thresholds do not ensure normal functional hearing (listening), since problems such as reduced speech recognition in noise, or sound localization may be present but remain undetected. Auditory processing is the medical term of listening. This review paper presents the nature of Auditory Processing Disorder, the valid testing approach, its aetiology, clinical populations that may have the disorder and how intervention and management are achieved according to current scientific evidence and clinical practice.
