Towards an Urban Vibrancy Model: A Soundscape Approach

Area of Science:

• Environmental Psychology
• Acoustics
• Urban Design

Background:

• Soundscape research often focuses on tranquility, neglecting actively engaging soundscapes.
• Predictive models for urban soundscape design are needed, especially for the vibrancy dimension.

Purpose of the Study:

• To establish a predictive model for soundscape vibrancy using physical parameters.
• To provide designers and practitioners with tools for managing actively engaging urban soundscapes.

Main Methods:

• A group interview identified influential factors for vibrancy perception.
• Laboratory experiments collected vibrancy perception data across UK and China locations.
• Physical aural and visual parameters were used as indicators in the predictive model.

Main Results:

• A predictive model incorporating Roughness, Presence of People, Fluctuation Strength, Loudness, and Presence of Music explained 76% of vibrancy score variance.
• Vibrancy scores correlated significantly with eventfulness but not pleasantness.
• Vibrancy perception is context-dependent, influenced by both auditory and visual elements.

Conclusions:

• The developed model offers a tool for predicting and designing vibrant soundscapes.
• Vibrancy is a distinct perceptual dimension influenced by a combination of sound and visual environmental factors.
• Future research should consider the interplay of soundscape and visual scenery in urban design.
