The Expression and Intervention Simulation of Underwater Noise Impact Based on VR Particle Soundscapes: From Noise Visualization to Participatory Strategy Development
Abstract
This study focuses on the underwater noise pressure endured by the Yangtze River finless porpoises in the context of shipping and coastal human activities, and explores how virtual reality can transform "invisible and difficult-to-perceive" noise pollution into perceptible visual and interactive experiences. The research objective is to construct a soundscapes expression framework based on typical noise sources and spatial characteristics of the Yangtze River, and in VR, create a set of visual grammar centered on a particle system using "medium distortion + particle density + frequency band layering form"; finally, design a strategy module to conduct interactive reasoning, and provide real-time feedback on noise distribution and ecological pressure indicators changes. The noise visualization method and participatory reasoning prototype enable the audience to intuitively understand noise intensity, spatial aggregation, and frequency band differences, and through strategy selection and combination, observe noise changes and form comparisons and scheme outputs. This is applicable to science popularization exhibitions, environmental education, and issue communication, helping the audience move from perceiving the problem to understanding its underlying mechanisms and trade-offs.
