强声效应的主观描述与定量评价

The subjective description and quantitative evaluation of strong sound

传统的有关噪声对人影响的描述与定量评价一般仅限于针对低强度的噪声(不至于引起听觉损伤的噪声)。近年来,由于强声问题日益受到关注,强声效应描述的研究变得尤为迫切。首先建立了初级描述词库,然后通过主观评价实验进行一系列筛选,最终获得强声对人心理效应的描述。此外,完成了不同强声物理属性(声压级、持续时间和频率)下的主观评价实验,获得了强声对人影响的定量描述数据,为后续强声效应建模研究奠定了基础。

Traditional description and quantitative assessment of noise effects on human beings is generally limited to low-intensity noise （no human auditory injuries）. In recent years, due to strong sounds draw more attention, research on strong sound effect description becomes urgent. This paper first builds a primary verbal description, makes a series of screening through subjective assessment tests, and finally obtains a descriptor of strong sound effect on human psycho-logical. Furthermore, by completing subjective assessment tests with different strong sound physical parameters （sound pressure level, duration and frequency）, and obtaining quantitative data of strong sound effect on human psychology, the basis for future modeling study of strong sound effect is provided.
