Purpose:
To develop and verify the usability of an internet-based system for telemonitoring and guidance of the hearing aid user as well as monitoring the long-term performance in a pilot group.
Methods:
The system "I can hear, but I can't understand" was developed based on recommendations in the literature regarding layout, design, and content for guidance and advice. Three stages were followed: planning, design and content development, and pilot testing. The sample consisted of 43 adults and older adults with any type and degree of hearing loss, who had been regularly using a hearing aid for at least 30 days and at most 24 months, with reading skills and no evidence of cognitive impairments. The individuals were followed up for 8 to 12 months. The users' performance was monitored with the Speech, Spatial and Qualities of Hearing Scale. The usability of this material was assessed with the System Usability Scale.
Results:
Improved performance and increased self-reported daily use of the hearing aid were observed after the period of guidance and telemonitoring via the system for all research participants. In all analyzes of the SUS scale, it was possible to observe a performance superior to 70 points, demonstrating good usability of the system. In the analysis of the performance of the SSQ, in the three moments of the research, a positive response was observed in all domains, thus showing progress in the use of hearing aids, with significant data for the domain of Hearing Speech.
Conclusion:
The system "I can hear, but I can't understand" proved to be an easy-to-use and effective tool to telemonitor hearing aid users.
