Abstract

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.
