When living close to an industrial plant, people are exposed to a combination of industrial noise sources and a background noise composed of all the other noise sources in the environment. As a first step, noise annoyance indicators in laboratory conditions are proposed for a single exposure to an industrial noise source. The second step detailed in this paper involves determining total annoyance indicators in laboratory conditions for ambient noises composed of an industrial noise source and a background noise. Two types of steady and permanent industrial noise sources are studied: low frequency noises with a main spectral component at 100 Hz, and noises with a main spectral component in middle frequencies. Five background noises are assessed so as to take into account different sound environments which can usually be heard by people living around an industrial plant. One main conclusion of this study is that two different analyses are necessary to determine total annoyance indicators for this type of ambient noise, depending on the industrial noise source composing it. Therefore, two total annoyance indicators adapted to the ambient noises studied are proposed.
当人们居住在工业工厂附近时，他们会同时暴露于工业噪声源和由环境中所有其他噪声源组成的背景噪声之中。作为第一步，本文提出了在实验室条件下针对单一工业噪声源暴露的噪声烦恼指标。本文的第二步详细涉及在实验室条件下确定由工业噪声源和背景噪声组成的环境噪声的总烦恼指标。研究了两种类型的稳定且持续的工业噪声源：主要频谱分量在 100Hz 的低频噪声，以及中频噪声。评估了五种背景噪声，以考虑到人们通常在工业工厂周围听到的不同声音环境。这项研究的一个主要结论是，需要进行两种不同的分析来确定这种环境噪声的总烦恼指标，具体取决于构成它的工业噪声源。因此，提出了两种适用于所研究环境噪声的总烦恼指标。
