【 摘 要 】

Research considers high frequency tonal audiometry as a tool for the early diagnosis of auditory alterations derived from etiological agents. AIM: to investigate possible differences in high frequency audiometry of individuals with normal hearing, based on the person who places the earphone. PATIENTS AND METHOD: clinical and experimental study with 55 undergraduate students from a country side branch of the São Paulo State University, with normal hearing, underwent two tests each; for the first, the evaluator positioned the earphone on the participant; for the second one, the participant did it by him/herself. An AC40 audiometer calibrated to emit pure tone was used in the frequencies of 10, 12.5, and 16 kHz. RESULTS: The kappa(k) coefficient statistical analysis was used to verify the agreement between the two ways of earphone positioning of earphone, bearing a ≥0.70 kappa value as a criterion. Results attained for both ears were below this criterion, with k average of 0.50. DISCUSSION: results indicate a risk of compromising the exam reliability when the patient him/herself adjusts phone to his/her own ear. CONCLUSION: when performing audiometric assessment, this variable must be considered in order to attain reliable results.
