Music, Arousal, and Mood: The Role of Loudness and Loudness Change in Cross-Cultural Music Perception

点击翻译按钮获取中文摘要

Despite decades of research into perception of Western music there are no studies applying experimental methods to perception of traditional Australian music. This project investigates a parameter present in all auditory events, from animal songs and alarms to music and speech: loudness. Results concerning the universality of loudness change and effects on mood and arousal will be reported to academic and local communities. Understanding how people experience loudness has implications for non-musical uses of sound, eg. more effective uses of loudness in non-verbal auditory warnings. Identifying effects of loudness on arousal and mood is also relevant to research on therapeutic or harmful effects of music and other sounds.
