title: Initial assessment of hearing loss using a mobile application for audiological evaluation.
abstract: OBJECTIVE
  This study aimed to compare an Apple iOS mobile operating system application for audiological evaluation with conventional audiometry, and to determine its accuracy and reliability in the initial evaluation of hearing loss.
  
  
  METHODS
  The study comprised 32 patients (16 females) diagnosed with hearing loss. The patients were first evaluated with conventional audiometry and the degree of hearing loss was recorded. Then they underwent a smartphone-based hearing test and the data were compared using Cohen's kappa analysis.
  
  
  RESULTS
  Patients' mean age was 53.59 ± 18.01 years (range, 19-85 years). The mobile phone audiometry results for 39 of the 64 ears were fully compatible with the conventional audiometry results. There was a statistically significant concordant relationship between the two sets of audiometry results (p < 0.05).
  
  
  CONCLUSIONS
  Ear Trumpet version 1.0.2 is a compact and simple mobile application on the Apple iPhone 5 that can measure hearing loss with reliable results.
