Measuring Cognitive Effort in Challenging Sound Environments
In a three-part study, that took place in the Centre for Applied Audiology Research (CAAR) at Oticon quarters in Denmark, participants are asked to perform various listening and memorization tasks in a noisy environment with and without passive noise damping, in which their performance is measured both subjectively and objectively. Two tests consist of the subjects listening to sentences where they should correctly identify certain words, with and without passive noise damping. The third test is a listening and recall test, again with and without passive noise damping. When the tests are complete subjects are asked questions related to their experience of the test subjectively, as well as having their pupil dilation measured throughout (an objective indicator of how much they must concentrate).
What We Found Out
Based on this study the researchers were able to conclude that passive noise damping in EPOS ADAPT 600 headsets improves cognitive performance – reducing listening effort by 35% and improving memory recall by 10%.
For today’s professionals working in noisy or unnatural sound environments this means that you can stay present and focus longer in hybrid meetings, reduce stress on your brain used while trying to understand what’s being said and better recall important information. At the end of a workday, professional audio tools that are designed for the hybrid worker are not only a necessity, but an advantage that helps you perform your best.
