Digits-in-Noise Trial

Large-scale hearing screening and auditory processing programs for school children, adults and the elderly are still restricted. Multiple factors account for this reality, including the cost and training of human resources to perform the procedure, the time required to perform it, and the cost of equipment. Smartphones have recently been used as hearing screening tools because they provide a low cost assessment, important for populations without access to diagnosis. Researchers from South Africa have developed of the digit in noise test (DIN) based on a smartphone app for hearing screening. This test is adaptive – the individual listens to the three-digit series and types them on the phone screen. This project aims at the translation, cross-cultural adaptation, validation and accuracy of DIN in Brazilian Portuguese in all age groups for the identification of hearing impairment and central auditory processing disorders.
