Discussion
Our study is one of the first to evaluate smartphone-assisted
audiometry as a hearing screening tool for populations that currently
have no access to formal audiometry. Results indicate that the iPhone
uHear application is reasonably accurate at screening for moderate
or worse (disabling) hearing loss. We found a sensitivity of 100%,
with a very high negative predictive value, implying an ideal test for
screening. The highest test accuracy (90%) was found in an SR, with
a specificity of 88%, rendering the least false positives. This highlights
the need for caution when testing in a WR setting.
