摘要

提出了一种基于对播放时长短时化处理的声音样本剂量值度量方法, 确定了十一种剂量值指标用于衡量具有固定播放时长声音样本的剂量值, 并分析了可能影响声音样本剂量值的主要因素; 随后, 对大量声音样本以各种指标度量的剂量值矩阵进行了聚类分析, 获得了三种类型的声音样本剂量值度量指标, 并确定了不同指标类型中的代表性指标; 最后, 分析了声音样本采用不同类型指标度量的剂量值与评价者对声音样本主观烦恼度等级之间的关系. 为利用主观评价实验进行固定播放时长声音样本作用下的主观烦恼度研究奠定了基础.

Abstract

The traditional measurements for environmental noise exposure-dose are inapplicable to the sound samples with fixed playing duration used in subjective evaluation experiment. In this paper, we propose a method for exposure-dose measurement of sound samples with fixed duration. The method based on the short-term exposure-dose values during the playing time of the sound samples. An entire analysis on the potential influencing factors are carried out, including the short-term analysis period, the statistical properties of the short-term exposure-dose values and four different frequency weightings. Then 11 indices are used to measure the exposure-dose of the fixed duration sound sample, which lays the groundwork for establishing the dose-annoyance relationships via subjective evaluating experiments.
