Article
Central auditory processing disorders are defined as deficits in the neural processing of auditory information in the central auditory nervous system with simultaneous normal hearing. Due to the inappropriate reception of speech sounds and difficulties in their understanding and reproduction, pupils may have difficulties in learning language, e.g....
