音频注入抑制噪声烦恼感的标准样本评价法

Standard sample evaluation method for noise annoyance suppression from audio injection

基于声能量降低的噪声控制技术以声压级为评价指标,近年来提出的加法控制技术以烦恼度为评价指标。但目前尚未提出将声压级变化值与烦恼度变化值联系起来的方法。以3种变电站噪声为目标声,以自然声和人工合成声为调控声,使用标准样本法进行纯音和叠加声烦恼度主观评价实验,得到烦恼度下降值与等效声压级变化值曲线,并定量分析音频注入下的烦恼感抑制效果,构建了加法控制与减法控制效果评价相互沟通的桥梁。研究结果给出了调控声对于变电站噪声的烦恼感抑制效果,为噪声控制效果的定量分析以及变电站噪声控制提供了新思路。

Noise control technology based on sound energy reduction uses sound pressure level as an evaluation index,and the addition control technology proposed in recent years uses annoyance as an evaluation index.However,no method has been proposed to link the change in sound pressure level with the change in annoyance.In this paper,three types of transformer substation noise are selected as the target sounds,natural sounds and synthetic sounds are selected as the controllable sound,and the pure tone annoyance and combined noise annoyance evaluation experiments are carried out using the standard sample method,and the curve of the decrease value of annoyance and the equivalent sound pressure level change value is obtained.And the effect of audio injection annoyance control is quantitatively analyzed,aiming to build a bridge between addition control and subtraction control.The research results show the effect of controllable sound on the annoyance of substation noise.This study provides new ideas for quantitative analysis of noise control effects and substation noise control.
