Recent Developments in Modelling Monaural and Binaural Quality Aspects (no manuscript)

Abstract:
Daily-life acoustic environments are often complex, typically comprising one attended target sound in the presence of other interfering sounds (e.g., disturbing talkers) and reverberation. To better understand hearing in such complex acoustic environments (CAEs), different perceptual measures such as detectability, speech intelligibility, audio quality, and loudness can be assessed. The resulting data are also important for the development of auditory models, which have often been applied under optimal conditions (i.e., without reverberation and maskers). Moreover, auditory models have often been developed or “tuned” to account for specific experiments. To overcome such limitations, a unified modelling approach, the Generalized Power Spectrum Model (GPSM; e.g., Biberger and Ewert. 2017, JASA., 142 (2), 1098–1111), has been suggested, using power and envelope power SNRs in combination with a task-dependent decision stage to predict psychoacoustic masking, speech intelligibility and audio quality. The model was initially “calibrated” using basic psychoacoustic experiments before it was applied to the more complex perception tasks. This talk provides an overview of current GPSM-based auditory model developments for audio quality, such as the combination with binaural audio quality models, and presents recent findings from an experimental study on audio quality perception in CAEs with normal-hearing listeners.
