... OAE tests tend to be quicker and less expensive because they do not require the use of electrodes. Costs for ABR electrodes vary, but many health-care organizations require the use of disposable electrodes in efforts related to infectious-disease control. The accuracy of OAE measurements depends on ...

This is due to restrictions in the approach, anatomical variations, and the relatively large diameter of the FMT (1.6 mm) as compared to the opening of the round window niche (1.3–1.6 mm) [8, 9]. Furthermore, permanently ...
