Audio-PSS: Development of product service systems in tele-audiology

Problem definition & objective

Loss of hearing is one of the most common functional limitations coming with age. It means a significant restriction in communication and social participation for those affected. According to a recent study, the rate of hearing-impaired people in Germany has been estimated at 15.7% (von Gablenz and Holube, 2015).

Modern hearing systems support those affected in improving their hearing. However, it requires a weeks-long and stressful adjustment phase of the hearing system to the subjective perceptions. High failure rates are the result. With some hearing aids, it is already possible to record device parameters for support. However, since this adaptation is based on individual data and the customer can only communicate his feelings subjectively, there is a lack of continuous technical support for the process.

The aim of the research project Audio-PSS is to increase the acceptance and comfort of modern hearing systems for the hearing impaired and to describe new business models for the hearing aid industry. For this purpose, innovative services based on a connected hearing system are developed, prototypically implemented and evaluated. These include digitally assisted hearing assistance, remote fitting and automated control of hearing aids.

Thanks to the location- and time-independent support, the functions are not only helpful in the adaptation phase, but also ensure a more comfortable operation. The focus of these services is both the improvement of the hearing experience and the customer care process. The data collected by connected hearing systems are also relevant for normal hearing people. Audio PSS therefore also shows how the data can be used for services outside the healthcare market, e.g. in the form of an acoustic restaurant index.
