Early detection of auditory changes in MDR TB – Validity of extended high frequency audiometry with a smartphone application
Background:
The extended high frequency range is essential in monitoring ototoxicity. With the rising prevalence of MDR-TB in Sub-Saharan Africa, as well as globally, there is a need to reach these patients. Therefore, smartphone-based extended high frequency audiometry with automated testing has the potential to provide affordable access to audiometry for patients at risk of ototoxicity in underserved contexts.
Purpose:
To validate the extended high frequencies for the threshold version of the validated smartphone application (hearScreenTM) with calibrated headphones.
Research Design:
A repeated-measures within-subject design was used whereby air conduction thresholds (8– 16 kHz) were determined by conventional audiometry and compared to smartphone-based audiometry using audiometric headphones (Sennheiser HDA 300 circumaural headphones) and non-audiometric headphones (Sennheiser HD202 supra-aural headphones).
Study Sample:
A total of 61 participants (122 ears) were included in the final analysis. Of these, 24 were adults with known exposure to ototoxic medications (mean age = 36.8 yr, SD = 14.2; 52% male, 48% female), and 37 were adolescents (mean age = 17.6 yr, SD = 3.2; 24% male, 76% female).
Data Analysis:
Threshold comparisons were made between conventional audiometry and smartphone-based audiometry with audiometric headphones and non-audiometric headphones. The paired samples t test were used for comparison of threshold correspondence between conventional and smartphone thresholds.
Results:
Conventional thresholds exceeding 10 dBHL corresponded with 83% of smartphone thresholds with standard audiometric headphones, and 84% of smartphone thresholds with non-standard audiometric headphones, within 10 dB or less. There was no significant difference between conventional audiometry and smartphone-based audiometry using standard audiometric headphones. There was no significant difference between conventional audiometry and smartphone-based audiometry using non-standard audiometric headphones except at 10 kHz (p < 0.05).
Conclusions:
The hearTest application with calibrated audiometric headphones and non-audiometric headphones, except at 10 kHz, provides a cost-effective option to determine valid air-conduction extended high frequency thresholds.
