| Περίληψη: | Purpose: Hearing loss is a major global health challenge, and pure-tone audiometry remains the gold standard for assessing auditory thresholds. However, conventional clinical audiometry requires specialized sound-proof booths, which limit its accessibility in resource-constrained settings. To address this limitation, we developed and evaluated a portable audiometry system, designated as the E200, incorporating active noise control (ANC) technology with integrated supra-aural earphones. Methods: In this 2-phase study, reference equivalent threshold sound pressure level calibration was first performed on 183 volunteers comparing E200 to conventional clinical pure-tone audiometric testing. Subsequently, we prospectively enrolled 114 participants with diverse otologic pathologies from tertiary otology clinics to evaluate the validity of the E200 audiometric system. Results: Data from 228 ears were collected from 114 participants, with 7 frequencies tested/ear, resulting in 1596 sets of data. The two one-sided test equivalence analysis demonstrated that all tested frequencies met the equivalence criterion at the ±5 dB margin. Pure-tone average (PTA) was derived from the arithmetic mean of air-conduction thresholds at standard speech frequencies (0.5, 1, 2, and 4 kHz), with hearing loss severity classified according to WHO (2021) criteria: normal (<20 dB hearing level [HL]), mild-to-moderate (20-<50 dB HL), and moderate-to-severe (≥50 dB HL). Both Bland-Altman plots and Cohen's κ statistics demonstrated good agreement with the PTA results. Conclusions: This ANC-integrated portable audiometer demonstrates promising potential for hearing screening outside conventional sound-proof booths; however, its long-term clinical value and practical applications require further investigation and validation. |
