چکیده

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.

Music, perceived arousal, and intensity: psychophysiological reactions to Chopin's "Tristesse".

The present study investigates the relation of perceived arousal (continuous self-rating), autonomic nervous system activity (heart rate, heart rate variability) and musical characteristics (sound intensity, musical rhythm) upon listening to a complex musical piece. Twenty amateur musicians listened to two performances of Chopin's "Tristesse" with different rhythmic shapes. Besides conventional...

What Constitutes a Phrase in Sound-Based Music? A Mixed-Methods Investigation of Perception and Acoustics

Phrasing facilitates the organization of auditory information and is central to speech and music. Not surprisingly, aspects of changing intensity, rhythm, and pitch are key determinants of musical phrases and their boundaries in instrumental note-based music. Different kinds of speech (such as tone- vs. stress-languages) share these features in different proportions and form an instructive comp...

Investigation on Pleasure Related Acoustic Features of Affective Speech*

This paper presents our recent work on the investigation of affective speech along the pleasure-displeasure (P) dimension in the PAD emotional space. First, 76 conventional features are taken as candidates. And a novel feature, F0 Dominant Ratio, which is designed to reflect the dominant pitch, is also introduced. Correlative coefficients are calculated and a preliminary selection is done. Fact...

Increased Arousal Levels and Decreased Sleep by Brain Music in Rats

⎯More and more studies have been reported on whether music and other types of auditory stimulation would improve the quality of sleep. Many of these studies have found significant results, but others argue that music is not significantly better than the tones or control conditions in improving sleep. For further understanding the relationship between music and sleep or music and arousal, the pr...

Research Paper: Do Computer Games Affect Arousal Level in Children With Attention/Deficit Hyperactivity Disorder?

Background: Attention-Deficit Hyperactivity Disorder (ADHD) is a common psychiatric complication in children, which affects about 5-10% of the population. Although ADHD is a multi-factorial disorder, one of its causes refers to dysfunction of the arousal. Objectives: The current study aimed at investigating whether a change in arousal level in children with ADHD differs from the control group....
