The validity of patient-operated smartphone-based Rinne test awaits further study. ConclusionĪ smartphone-based Rinne test was validated for the detection of an air–bone gap ≥ 25 dB at 512 Hz in the clinical setting. The smartphone-based Rinne could not evaluate two patients with a moderately severe/severe sensorineural hearing loss due to their inability to detect the vibrations. The smartphone-based Rinne test could correctly discriminate between patients with an air–bone gap ≥ 25 dB at 512 Hz from patients with a lower or no air–bone gap at 512 Hz. The Sensitivity was 85% for both tests, specificity was 90% and 93% for smartphone and tuning fork tests, respectively. The overall agreement between the traditional Rinne test and the smartphone-based test was 98%. The test results were compared to those of formal audiometry. Each participant underwent the traditional 512 Hz tuning fork-based Rinne test, as well as a smartphone-based Rinne test by means of a single uncovered smartphone with a vibration application. Twenty consecutive patients hospitalized in the otolaryngology department of a tertiary medical center due to unilateral hearing loss (HL study group), and 30 consecutive inpatients on the same ward who had no otological history (controls) were enrolled. To validate a smartphone-based Rinne test employing the vibration application of mobile telephones.
