本文借助单一声样本与人工合成的混合声样本,重点研究了由多个单一声源共同作用形成的混合声的剂量值预测方法.首先,提出了一种基于对作用时长短时化处理的声音样本剂量值确定流程,并利用该方法分别确定了单一声样本与人工合成的混合声样本的剂量值.随后,分析了混合声样本剂量值(亦称总剂量,记为LTotal)与构成混合声样本的每个单一声样本剂量值(亦称组分剂量,记为Li,i=1,2,···,K;K为单一噪声样本的个数亦称组分数量)之间的关系,实现了在已知所有单一声剂量值的前提下成功预测混合声的剂量值,为深入开展复杂声环境下的噪声源控制和噪声总剂量控制、实现高效的环境噪声治理提供了理论依据.
In this paper, a single acoustic sample and artificial mixed acoustic sample, focusing on a single sound source formed by a combination of mixed-sound dose dose prediction method.First of all, based on the action of a short duration of the sound Sample dose value determination process, and the use of the method to determine the single acoustic sample and synthetic mixed sample of the acoustic dose.Then, the analysis of the mixed acoustic sample dose value (also known as the total dose, denoted as LTotal) constitute a mixed sound The relationship between the dose value (also referred to as the component dose, denoted as Li, i = 1,2, ..., K; the number of single noise samples, also referred to as the component amount) of each single sample of a sample , The successful realization of the mixed acoustic dose value under the premise of knowing all the single sound dose values has provided a theoretical basis for further carrying out noise source control and total noise dose control in a complex acoustic environment and realizing efficient environmental noise control.
