Using a communication device in noisy environments increases the effort needed to listen and understand the received speech signal. Since this (near-end) noise cannot be reduced, various techniques are applied in different devices: Active noise cancellation (ANC) in headsets, various types of near-end listening enhancement (NELE) in handsets and hands-free and in-car communication (ICC) systems in vehicles. Qualification and optimization of these implementations is key for the market success and a good user experience. To give an overview over challenges and advantages of evaluating listening effort of communication devices, HEAD acoustics will host a free online seminar on September 1, 2020.
