Central auditory processing disorder (CAPD), also known as auditory processing disorder (APD), is a group name for a number of disorders that affect the hearing process. Although people with CAPD have normal hearing, their brain is unable to process and make sense of what they are hearing.
CAPD affects both adults and children. It causes difficulty in understanding language due to a distortion of the auditory (hearing) signal. Some main traits of CAPD in children are the inability to decipher speech in noisy places, difficulty following directions and conversations, poor decoding skills, distraction and learning difficulties.
