Knowledge and Expectations of Hearing Aid Applications: A Cross-sectional Survey of Smartphone Users and Hearing Professionals
ABSTRACT
Background:
Despite the increasing prevalence of hearing loss, the cost and psychological barriers to use of hearing aids may prevent individuals with hearing loss from using these aids. Hearing loss patients can benefit from smartphone-based hearing aid applications (SHAAs), which are smartphone applications that use a mobile device as sound amplifier.
Objective:
The aims of this study were to determine how ear, nose and throat (ENT) outpatients perceived SHAAs, analyze factors that affected this, and estimate costs of annual subscription to an application through a self-administered questionnaire survey of smartphone users and hearing specialists.
Methods:
The study employed cross-sectional, multi-center survey of both ENT outpatients and hearing specialists. The questionnaire was designed to collect personal information about the respondents as well as responses to 18 questions concerning SHAAs in 5 domains: knowledge, needs, cost, expectations, and information. Questions about the expected cost of SHAAs were included in the questionnaire distributed to hearing experts.
Results:
Among 219 smartphone users and 42 hearing specialists, only eight respondents (3.7%) recognized SHAAs, while 47 of 261 respondents (21.5%) reported considering using an assistive device to improve their hearing capacities. Average perception score was 2.81 (95% CI 2.65-2.97), lower than the grade point average of 3. Among factors that shaped perceptions of SHAAs, the needs category received the lowest scores (2.02, 95% CI 1.83-2.20) whereas the cost category received the highest scores (3.29, 95% CI 3.14-3.44). Age was correlated with the information domain (P = .000) and an increased level of hearing impairment resulted in significantly higher points in the needs category (P = .000). Patients expected the cost of an annual application subscription to an SHAA to be about 86 USD, and predicted cost was associated with economic status (P = .200) and was noticeably higher than the prices expected by hearing specialists (P < .001).
Conclusions:
Outpatients expected SHAAs to cost more than hearing specialists. However, SHAA perception was relatively low. In this regard, enhanced awareness of SHAAs is required to popularize SHAAs. Clinical Trial: None
