Scientific Whitepaper 2022 - “The effects of noise attenuation on listening effort and arousal”
We’re committed to validating our technologies and unique scientific approach through innovative research
This whitepaper presents the results of a clinical study* that investigated the benefits of passive damping technology used in EPOS Enterprise and Gaming solutions. The intent was to demonstrate how damping effects the listening effort exerted by the study’s participants.
The psychoacoustic research was conducted by EPOS in the Centre for Applied Audiology Research (CAAR)1, Oticon, Denmark, with a focus on pupillometry tracking, speech recognition performance and subjective ratings for pre- and post-load tasks for each noise condition. The users performed the listening tasks with and without EPOS passive damping.
By analyzing the results of the tests, we can conclude that the passive noise reduction performance of EPOS headsets leads to a reduction in effort listening, better memory recall and higher levels of word recognition.
This type of in-depth scientific research has been a key element in the development of audio solutions built on EPOS BrainAdapt™ technology, which support the brain’s natural way of processing sound. The custom-made components, acoustics and sophisticated algorithms that go into EPOS solutions ensure maximum cognitive performance, even in challenging sound environments.
The results of this study have been presented and reviewed at scientific conferences including the International Hearing Aid Research Conference (IHCON) 2022, Lake Tahoe, USA and the International Conference on Cognitive Hearing Science for Communication, Linköping, Sweden.
