Evaluation and User Studies

The Oldenburg Branch for Hearing, Speech and Audio Technology HSA has access to different laboratories and special rooms for evaluation studies as part of the cooperation with the Haus des Hörens and the University of Oldenburg. The communication acoustics simulator allows simulation of the acoustic characteristics of practically any room, such as classrooms, offices or even railway station concourses. A central database with over 2,400 test persons is available for performing customer studies. This allows test persons to be selected according to specific criteria such as age, sensory impairments or technology acceptance and technical competence. In addition to qualitative and quantitative user survey methods, the scientists use new neuroergonomic methods to measure the cognitive load involved in use of products and technologies.
