Audio-Visual Perception of Loudness in Concert Halls
* Presenting author
Abstract:
The adequate level of loudness is one of the key components that is strongly linked to the audience’s assessment of the acoustical performance of a concert venue. Previous studies on loudness perception revealed that listeners’ judgement of loudness is influenced also by the visual cues which include source-receiver distance. Contrary to expectations, the same sound levels are often judged louder in seating positions further away from the stage as shown in the previously conducted psycho acoustics studies. Following the previous literature, the present work aims to elucidate and review the masking effect of visual cues on the perception of loudness though a series of listening tests with blind vs visual inputs. The preliminary listening test is going to be conducted in VR setup with virtual loudspeaker orchestra auralizations of the Gasteig Concert Hall in Münich. A live demonstration of the test will accompany the presentation.
