Variabilidade teste-reteste na audiometria tonal: comparação entre dois transdutores

Abstract

Purpose:To characterize the test-retest variability with supra-aural and insert earphones and compare the pure tone thresholds between the transducers. Methods: Seventy-four individuals of both genders with normal hearing and tympanometric curve of type A were selected. All subjects underwent anamnesis, meatoscopy, air conduction pure tone audiometry, either with the supra-aural earphone, or with insert earphone and speech audiometry. After this initial evaluation Acoustic Impedance Tests were performed. Finally, pure tone audiometry procedures were repeated with both transducers. Results: Supra-aural earphone produced higher test-retest variability when compared to the insert earphones.

Treatment Outcome of the Bony Obliteration Tympanoplasty Versus Nonobliterative Techniques in Cholesteatoma Surgery: A Retrospective Analysis

“…Evaluation of audiological results showed no significant change in AC threshold level between pre- and postoperative after BOT and CWD surgery but a significant improvement in AC threshold level after CWU surgery. However, this improvement is very small and may not be clinically relevant as the median hearing improvement of 3.8 dB in this group is lower than the test–retest reliability of 5 dB in pure tone audiometry (13). The audiological results for individual cases are demonstrated in the hearing plots (Fig.…”
