Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Summary

Smartphone hearing test apps show high accuracy for identifying hearing loss. These tools, e-audiologia (EHT) and Yuichi Sakashita (YSHT), correlate well with traditional pure tone audiometry (PTA), suggesting potential for widespread use.

Area of Science:

Audiology
Digital Health
Medical Diagnostics

Background:

Smartphone applications (Apps) have surged in healthcare use post-COVID-19.
Self-hearing test Apps are now accessible on Android and iOS platforms.
The diagnostic accuracy of these mobile health tools requires investigation.

Purpose of the Study:

To evaluate the diagnostic accuracy of smartphone self-hearing test Apps.
To compare app-based hearing assessments with conventional pure tone audiometry (PTA).

Main Methods:

Prospective study of 38 adult patients (age 20-68) at an Audiovestibular Medicine Clinic.
Utilized e-audiologia (EHT) for Android and Yuichi Sakashita (YSHT) for iOS.
Compared app-derived hearing thresholds against gold standard PTA, defining hearing loss based on specific decibel levels at key frequencies.

Main Results:

Combined Apps achieved 100% sensitivity and 76% specificity.
Strong positive correlation (p < 0.001) observed between app thresholds and PTA.
Maximum mean difference between app and PTA thresholds was 10.5-dB HL at 500 Hz.

Conclusions:

EHT and YSHT Apps demonstrate significant potential for hearing screening and disorder monitoring.
These apps can be integrated into primary care, audiology clinics, nursing homes, and public health initiatives.
Smartphone hearing tests offer a viable tool for accessible audiological assessment.
