Listener perceptions of changes in the arousal expressed by classical music have been found to correlate with changes in sound intensity/loudness over time. This study manipulated the intensity profiles of different pieces of music in order to test the causal nature of this relationship. Listeners (N = 38) continuously rated their perceptions of the arousal expressed by each piece. An extract from Dvorak's Slavonic Dance Opus 46 No 1 was used to create a variant in which the direction of change in intensity was inverted, while other features were retained. Even though it was only intensity that was inverted, perceived arousal was also inverted. The original intensity profile was also superimposed on three new pieces of music. The time variation in the perceived arousal of all pieces was similar to their intensity profile. Time series analyses revealed that intensity variation was a major influence on the arousal perception in all pieces, in spite of their stylistic diversity.
已经发现，听众对古典音乐所表达的兴奋感变化的感知与声音强度/响度随时间的变化有关。本研究通过操纵不同乐曲的强度曲线，以测试这种关系的因果性质。（实验中）听众（N=38）持续对每首乐曲所表达的兴奋感进行评价。从德沃夏克的《斯拉夫舞曲》作品 46 号第 1 首中提取一段音乐作为变体，改变其强度变化的方向，同时保留其他特征。尽管只是强度发生了反转，但是兴奋感也发生了反转。原始强度曲线也叠加在三首新乐曲上。所有乐曲的感知兴奋感的时间变化与其强度曲线相似。时间序列分析表明，尽管风格多样，但强度变化是所有乐曲兴奋感感知的主要影响因素。
