Validation of web-based audiometry version of HEARZAP.

Aim: The purpose of this study was to verify the accuracy of the web-based audiometer HEARZAP in determining hearing thresholds for both air and bone conduction.

Method: Using a cross-sectional validation design, the web-based audiometer was compared to a gold standard audiometer. Participants in the study totaled 50 (100 ears), of which 25 (50 ears) had normal hearing sensitivity and 25 (50 ears) had various types and degrees of hearing loss.
