Hearing aids in focus: This is how modern technology improves your hearing!

On May 6, 2025, Dr. Hendrik Husstedt will give an important inaugural lecture at the University of Lübeck. The theme of his presentation, “Between Testing and Research in Hearing Acoustics,” aims to highlight the challenges and advances in the study of innovative hearing technologies. The event begins at 5:00 p.m. in the AM4 lecture hall and offers insights into the central role of human hearing in everyday experience.

Hearing is essential for the perception of a variety of sounds and plays a central role in acoustic communication. Loss of this ability has far-reaching effects on the quality of life of those affected and their families. Modern hearing systems, particularly air conduction hearing aids, are technical achievements that address these challenges. They work by recording ambient noise, amplifying it and suppressing disturbing noises through signal processing.

Technology and benefits in hearing acoustics

Dr. In his lecture, Husstedt will explain how air conduction hearing aids work, including automation techniques for recognizing different hearing situations. A key aspect of these devices is the need for new developments to actually give users an advantage. One challenge is that the reimbursement of costs by statutory health insurance companies often depends on the benefits of these technologies compared to the existing deficit.

The individual selection of hearing aids is crucial and requires a comprehensive comparison of the functionality. In order to optimize this selection, quality assurance is necessary to test the various devices for their performance. Dr. Husstedt will lead technical measurements and listening tests that demonstrate the effectiveness of new technologies, highlighting the challenging research landscape in hearing acoustics.

Acceptance and use of hearing aids

Despite advances in technology, adoption of hearing aids remains a challenge. A recent overview analysis of the factors that influence hearing aid use shows that many people with hearing loss are hesitant to choose care. According to a study by Knoetze et al. (2023), both audiological and non-audiological factors are crucial for acceptance.

From an audiological point of view, the extent of the hearing loss and the self-perception of those affected are crucial. People with significant hearing loss are often more willing to accept hearing aids. In addition, the expectations of the technology significantly influence the decision to use it. Social support from family and friends can also have a positive influence on acceptance, while fear of stigma and financial resources represent significant barriers.

The financial aspects are crucial, as better financial resources increase the likelihood that people will choose hearing aids. A sensible measure to improve the situation could be the introduction of educational campaigns and the use of modern technologies such as tele-audiology to reduce barriers and increase accessibility.

In summary, it can be said that the inaugural lecture by Dr. Husstedt will not only address technical aspects of hearing acoustics, but also the social challenges and the need for acceptance of hearing aids against the background of modern research.
