Resumé

The technical components and software features of a new hearing-aid compatible smartphone-based ecological momentary assessment (EMA) system are presented in this paper. EMA is an assessment strategy that seeks to minimise instrumental infliction on the measured entity while data is gathered at multiple points of time. This work builds upon an already developed and deployed smartphone-based system. Objective data is gathered in the form of acoustical features, while subjective data is collected via automatised questionnaires. Since linking objective acoustical measures to subjective assessments is particularly promising with regard to the hearing rehabilitation process, our system has been specially tailored for hearing aid users. The introduction of wireless data transfer has eliminated cable clutter, a customisable questionnaire allows for subjective assessment, and a streamlined user interface complements the design. Like the former version, the current revision ensures the privacy of both participants and third parties. To facilitate cooperative research, source code and custom-built hardware will be released under open source licenses. All additional components are commercially available.
