AB  - BACKGROUND: Automated hearing tests have the potential to reduce the burden of 
      disease amongst learners by introducing such services within the school context. 
      METHODS: The aim of the study was to conduct a validation study on normal and 
      hearing impaired learners, comparing air and bone conduction automated test 
      results to conventional test results in 50 school aged learners (n = 100 ears) 
      within a noise controlled school environment using a cross sectional comparative 
      study design. The KuduWave 5000 (Emoyo.net) was used in this study. DATA 
      ANALYSIS: The spearman's correlation coefficient was calculated to determine 
      test-retest reliability. The mean and standard deviation (SD) was measured for 
      each frequency. The absolute mean difference (AMD) and SD was calculated for both 
      air and bone conduction testing at each frequency for automated testing. A paired 
      sampled t-test and a one way ANOVA was used to identify any significant 
      differences. Alpha was set as 0.05. RESULTS: There was significant correlation 
      between thresholds obtained for automated test one and test two for normal 
      hearing and hearing impaired group. The spearmans correlation coefficient was 
      high (close to +1) for majority of the results for both groups across the 
      frequency range. Both air and bone conduction testing across the frequency range 
      of 250 Hz-2000 Hz and at 8000 Hz were not statistically signfiicant (p < .005) 
      for both groups, however at 4000 Hz for bone conduction testing in the hearing 
      impaired group, there was a statisticially signficant difference (p = .003). This 
      was attirubted to the variaibilty in bone conduction test results often due to 
      force and placement of the bone vibrator. CONCLUSION: The findings indicate that 
      automated audiometry can yield relaible results that are comparable to 
      conventional test results. Key clinical considerations include extending the 
      response time, regular rest periods, improving instructions and comfort levels.
