Abstract:	Objective: Phone- and tablet-based hearing testing systems are now widely available. Here, we evaluated one such system from TympaHealth by comparing air conduction thresholds and resultant hearing aid targets and output, measured with the TympaHealth system with those measured using standard audiometry. Design: The hearing thresholds of 35 adults were measured using standard audiometry and the TympaHealth system. Each set of thresholds was used to generate NAL-NL2 targets and program a hearing aid. The data from each system were compared. Results: Bland--Altman analyses showed overall mean differences between thresholds measured with each system to be small, with 85% of TympaHealth thresholds being within ±5 dB of the standard audiometric thresholds, although TympaHealth thresholds were higher (poorer) than the standard audiometric thresholds. The hearing aid targets and gains generated from the standard audiometric thresholds were lower (less amplification) than those generated from the TympaHealth thresholds but again, mean differences at each frequency were small and likely imperceptible. Conclusion: These findings support the possibility that valid hearing testing can take place outside of a clinical booth using portable systems like that from TympaHealth, opening up the possibility of testing hearing and fitting hearing aids through pharmacies, opticians, and in care homes.
