Problems solved by technology

[0002] When evaluating and optimizing the sound insulation performance of different panels, there are two situations that will make researchers fall into a difficult situation where they cannot make a choice
The first case is that the weighted sound insulation of different boards is exactly the same, and the spectrum curves are interlaced with each other, and the difference is not large; the second case is that the weighted sound insulation of the former is higher than that of the latter Higher, but combined with the significant frequency band of the noise source, the sound insulation of the latter is better than the former in this frequency band, which makes the evaluation results and actual use results contradictory, and it is impossible to accurately test the results

Abstract

A sound insulation evaluation method and device provided by the present invention, according to the comparison and calculation of the sound insulation of the sample and the designated noise source, the unfavorable deviation is obtained; the unfavorable deviation is calculated to obtain the single-valued evaluation of the sound insulation performance; according to The evaluation quantity is used to obtain the evaluation result, so as to more accurately reflect the applicability of the sample to the specified noise source.

Description

technical field [0001] The invention relates to a sound insulation evaluation technology, in particular to a sound insulation evaluation method and device. Background technique [0002] When evaluating and optimizing the sound insulation performance of different panels, there are two situations that will make researchers fall into a difficult situation where they cannot make a choice. The first case is that the weighted sound insulation of different boards is exactly the same, and the spectrum curves are interlaced with each other, and the difference is not large; the second case is that the weighted sound insulation of the former is higher than that of the latter However, combined with the significant frequency band of the noise source, the sound insulation of the latter is better than that of the former in this frequency band, which makes the evaluation results and actual use effects contradictory, and it is impossible to accurately test the results.
