Measuring In-Car Communication Quality with HEAD acoustics Automated Test Suite Following ITU-T P.1150 Recommendations

To ensure a base level of functionality and quality of in-car communication (ICC) systems, the ITU-T International Standardization Sector has defined appropriate tests in Recommendation P.1150. German audio test and measurement solutions company HEAD acoustics has now implemented this recommendation in its ACQUA software with automated test sequences that can be applied for communication quality analysis, thus enabling comprehensive acoustic measurements of ICC systems and components.

HEAD acoustics will promote a new online presentation titled "Optimizing Listening Effort in Vehicles." This new free online seminar - October 13, 2020 - will address HEAD acoustics's vast research in both communications and automotive audio, detailing how to explore the company's listening effort evaluation tool called ABLE (Assessment of Binaural Listening Effort). This implementation allows researchers to evaluate listening efforts inside vehicles, including for telecommunication applications.

HEAD acoustics is promoting a new free online seminar dedicated to communications under noisy conditions, evaluation of the listening effort, and detailing the company's own efforts towards a perceptual-based method targeting the objective prediction of that listening effort under variable communication conditions and using different devices. A very relevant topic in current times, discussed online by top experts in the field, September 1, 2020.

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 will present its latest testing solutions for headphones and headsets at the upcoming AES International Conference on Headphone Technology in San Francisco, August 27 - 29. The company will show all that’s needed for product development and evaluation, including speech and audio quality testing, Active Noise Cancellation (ANC) performance evaluation, realistic background noise simulation, and a new measurement method for listening effort.
