Hearing Acoustics at the Belt (HABelt)


Funded by: European Union – Interreg 5a (Germany-Denmark), Network project

Duration: 01.07.2022 - 30.06.2022

Partners: University of Southern Denmark - Research Unit of Oto-Laryngology, Technische Hochschule Lübeck


We extend the international collaboration within the area of hearing acoustics and audiology between Germany (Lübeck) and Denmark (Odense) in a network project. The first goal is the development of a hearing aid demonstrator protptype, with the long-term goal to make the benefits of hearing aids more experiencable and contribute to better hearing support in both countries.

Direction-dependent Reference Curves for the Freiburg Monosyllabic Speech Test (RIBREFREI)


Funded By: BMWi WIPANO - Transfer of Knowledge and Technology by Patents and Standards

Duration: 01.09.2021 - 30.08.2023

Partners: Jade University of Applied Sciences Oldenburg


The main goal is to record standard reference curves for the Freiburg monosyllabic speech test in noise for different spatial arrangements of speech and noise. A special focus is the assessment of the influence of room acoustics on speech intelligibility in conditions where speech and noise are spatially separated.


Occlusion effect with variations of hearing aid coupling


Funded by: KIND Hörstiftung

duration: 01.10.2020 - 30.06.2021


For various individual earmold designs, the subjective and objective occlusion effect and further tramsmission parameters of a coupled hearing aid are determined. This allows to assess the compromise between the perception of the own voice and functionality of the hearing aid for different earmold designs, and to identify (non-) optimal designs for practical use.
