以等响处理后的 75 个稳态低频噪声样本为例, 采用成对比较法, 设计并完成了有 24 位评价者参与的大规模实验室主观评价实验。研究发现: 1)“不愉悦度”能够充分体现人对低频噪声的主观感受, 评价效果理想; 2) 存在决定低频噪声不愉悦感的频率或频带; 响度在决定稳态低频噪声的不愉悦感程度中占主导地位, 尖锐度的影响亦不容忽视; 与总声能相比, 低频段声能比与频谱形状在决定不愉悦程度时, 作用更大一些。 Taking the 75 steady-state low-frequency noise samples after equal-sounding as an example, the paired comparison method was used to design and complete a large-scale laboratory subjective evaluation experiment involving 24 evaluators. The results show that: 1) “unpleasantness” can fully reflect the subjective perception of low frequency noise, and the evaluation result is satisfactory; 2) there is a frequency or frequency band that determines the unpleasant feeling of low frequency noise; the unpleasantness of loudness in determining steady-state low frequency noise The dominant degree of intensity, the sharpness of the impact can not be ignored; compared with the total acoustic energy, low frequency sound energy ratio and spectral shape in determining the degree of unpleasantness, a greater role.
