HEAD acoustics ACQUA Adds Listening Effort Prediction Option

With LEAP (Listening Effort Prediction from Acoustic Parameters) now integrated into ACQUA 6.1.100, HEAD acoustics offers an optional tool for on-site prediction of the perceived listening effort. The software predicts the perceived listening effort of a listener when hearing an impaired speech signal without the need for an undisturbed reference signal. This makes it possible to carry out measurements more efficiently under laboratory conditions and in real-world applications.

HEAD acoustics Introduces ViBRIDGE Holistic In-Ear Headset Testing Solution

As many audioXpress readers already learned from reading the article by Hans W. Gierlich on the Benefits of Using Structure-Borne Sound in Headset Signal Processing, HEAD acoustics created a complete test solution for in-ear and headset devices using bone-conduction sensors. There are good reasons for developers and manufacturers to explore the use of bone-conduction sensors and test them with the new ViBRIDGE solution.

Practical Test & Measurement: The Benefits of Using Structure-Borne Sound in Headset Signal Processing

Practical Test & Measurement: The Benefits of Using Structure-Borne Sound in Headset Signal Processing

This article looks at the practical test and measurement of bone conduction technology, as used in product development for headsets and in-ear devices. It showcases new possibilities for manufacturers to better evaluate device performance, since no appropriate test equipment and methods were commercially available until now. The approach, complements a Head-and-Torso Simulator (HATS) with an actuator capable of generating structure-borne sound in the artificial ear. This way, a realistic simulation of the human structure-borne voice signal for in-ear headsets is possible.. This article was originally published in audioXpress, January 2023.
