Method for improving acoustic subjective evaluation indexes of medium-low pressure gas pressure regulating box

Abstract

The invention relates to a method for improving acoustic subjective evaluation indexes of a medium-low pressure gas pressure regulating box, and relates to the technical field of sound absorption andnoise reduction of the medium-low pressure gas pressure regulating box. The method comprises the following steps that S1, noise data radiated to the outside by the gas pressure regulating box is obtained; S2, the subjective evaluation indexes of the noise data sound quality are obtained; and S3, the sound quality of the gas pressure regulating box is optimized, the subjective evaluation indexes ofthe noise data of the gas pressure regulating box are analyzed, noise energy grading is carried out, and the structure of the gas pressure regulating box is optimized according to different noise discharge energy after grading so as to improve the sound quality of the gas pressure regulating box. The method has the effect of improving the acoustic subjective evaluation indexes of the medium-low pressure gas pressure regulating box with different noise pollution levels.

Description

technical field [0001] The present application relates to the technical field of sound absorption and noise reduction of medium and low pressure gas surge tanks, in particular to a method for improving the acoustic subjective evaluation index of medium and low pressure gas surge tanks. Background technique [0002] In recent years, with the continuous improvement of the implementation of environmental protection policies, the use of clean energy in my country has become more and more extensive. Natural gas is the main force of clean energy, and its usage and penetration rate are also increasing year by year, which has brought about the rapid development of the city gas industry. A large number of medium and low pressure gas surge tanks are an indispensable part of every city's gas operation network, and most of them are distributed in noise-sensitive areas such as residential areas and mixed commercial and residential areas. These areas are categorized as Class 1 and Class ...

AI Technical Summary

Problems solved by technology

[0003] Previous related research mainly focused on the noise control of urban gas high-pressure regulator station boxes or gate stations with more serious noise pollution. Spectrum analysis, but more and more complaint records show that many of this type of surge tanks that meet the emission standards or partially meet the standards (during the day) have also received complaints from nearby residents, etc.
