Amblyaudia represents the spectrum of auditory processing deficits auditory processing deficits(APD) that are felt to be associated with asymmetric hearing loss (AHL) and may have detrimental effects on hearing and language development. The hallmark finding in amblyaudia is an abnormally large asymmetry between the two ears during dichotic listening tasks with either normal or below normal performance in the dominant ear. Imbalanced signaling between the two ears during critical periods may result in altered or maladaptive patterns of neural connections that persist even after the peripheral pathology has resolved. Amblyaudia often presents with difficulties in attention, speech comprehension, and reading. Dichotic listening tests are used for screening and diagnosis because they put stress on the binaural auditory system and reveal any asymmetry between the auditory pathways. The prevalence and severity of amblyaudia in the population can be minimized by early identification and correction of AHL. Intervention may be in the form of reducing the intensity of input to the dominant ear during dichotic listening tasks or as a short-term intervention program called auditory rehabilitation for interaural asymmetry. Amblyaudia is an important source of difficulties in attention, speech comprehension, and reading, often difficult to diagnose, and early diagnosis and implementation of corrective measures can make a significant difference in the development of these children.
