低音刺激对主观情绪感知的影响

The influence of low-frequency sound on subjective emotion perception

以低频噪声对人的心理影响机理为基础,从低音可改变主观情绪感知的角度,采用等级评定法进行了主观评价试验。试验信号包括了低频多频声和1/3倍频程窄带信号两类,试验结果显示,低音可以增强被试的唤醒程度、使被试感觉受到信号的影响和支配,以及引起较为明显和强烈的烦恼感、空间感和带入感,可以增强主观情绪感知。该试验结果可应用于利用低音来增强电影情感方面。

Based on the theoretical assertion that low-frequency noise has a significant influence on people,an experimental evaluation of subjects is conducted by using the graphic rating scale method.The hypothesis of this test is that low-frequency sound could modulate people’s emotional response and subjective perception.The multifrequency sound and the narrowband signals of 1/3 Octave range,which are all at low frequencies are used as the test signals.The obtained results show that low-frequency sound could enhance subjective emotional perceptions,such as elevating arousal levels,causing subjects to feel overwhelmed by the perceived“domineering”effect of the sound,and causing intensified sensations of annoyance as well as altered perceptions of space and immersion.This scientific discovery could be applied to enhancing and manipulating the emotion experience of sensory media such as film,through the strategic use of low-frequency sound.
