“An acoustically transparent hearing system”
Hearing aid algorithms are increasingly capable of achieving improvement in complex acoustic situations under laboratory conditions for those affected. An open question is to what extent results obtained under laboratory conditions can be transferred to real-life situations of hearing aid users. Typically, this experience is only made individually by those affected during the care phase. In order to be able to make a better, and possibly also more individual, prediction of the hearing aid benefit in advance, a more recent development in the field of research is to use complex reproduction systems that permit realistic reproduction even of dynamic multi-source scenarios. This makes it possible to “bring reality into the laboratory” within certain limits.
In this presentation, I shall show how TASCAR (Toolbox for Acoustic Scene Creation and Rendering) is used in hearing aid research to determine individual hearing aid benefit for test subjects. Exemplary study results are presented that show auditory perception in complex situations in a simulated environment for normal and hearing impaired listeners. This applies to both “classic” speech intelligibility and more complex paradigms such as spatially-dynamic perception.
