Introduction: Hearing screening through smartphones is an attractive strategy because it is self-manageable, affordable and affordable. The use of speech materials, such as digits, in the presence of background noise, makes hearing screening more sensitive to identify hearing loss, since they simulate everyday situations. Objective: 1) To identify the effectiveness of cellular applications for the detection of hearing loss through a systematic review and 2) to verify the accuracy of the software-based noise test in Brazilian Portuguese. Method: The research presents two studies: a systematic review and a study of accuracy, in the first, the sample was composed by 12 diagnostic articles that used smartphone applications for hearing screening; In the second one, 186 subjects were evaluated by means of the audiological tests considered gold standard in the diagnosis of hearing loss and the Software-Based Noise Test in the Portuguese version. Results: In the one study it was observed that all 11 applications studied showed values of sensitivity and specificity favorable to diagnostic tests (AUC> 60%). In the second study, the Noise Digit Test presented a final cut-off point of -6.9dB for the pass / fail criterion, 92.7% sensitivity and 67.1% specificity. Conclusion: The systematic review provided significant information to show which applications may be considered the most effective in identifying hearing loss and the accuracy study inserts TDR in Portuguese as a new effective method of hearing screening
