Practical Test & Measurement: Objective Listening Effort Evaluation

This article by Hans W. Gierlich and Jan Reimes - two top experts in communication technologies from HEAD acoustics GmbH - details the expanded effort for understanding speech under noisy conditions, and addresses a new approach recently introduced by HEAD acoustics, resulting in a new model that can be used to test active noise cancellation (ANC) performance in complex scenarios where the system needs to distinguish between speech signals as part of the background noise and speech signals directed toward the users of these devices. This article was originally published in audioXpress, April 2020.

HEAD acoustics ABLE Automatically Assesses Perceived Listening Effort of Speech

Environmental noise impairs the intelligibility of received speech signals in headphones, mobile phones, in-vehicle hands-free terminals and in-car communication systems. In order to evaluate the influence of background noise on speech signals automatically and reproducibly, HEAD acoustics has developed “ABLE” (Assessment of Binaural Listening Effort), a method to predict perceived listening effort, available as a new option for the measuring and analysis software ACQUA.
