室内空间中人造板的隔声性能及规律研究

Study on the Sound Insulation Performance and Rules of Artificial Boards in Indoor Spaces

人造板作为室内装饰、装修的重要材料之一,会对室内空间的声学环境产生重要影响,研究人造板在室内空间中的隔声性能具有重要意义。基于此,本研究分别对人造板单板结构、箱框结构和以石膏板为背板的箱框结构的隔声性能进行分析。结果表明,板材类型对隔声性能具有显著影响,在单板结构中胶合板相较其它板材具有良好的隔声性能;箱框结构能够显著提高单板结构的隔声性能,五种人造板制成的箱框结构的隔声量分别提升了30.77%(中纤板)、7.14%(胶合板)、29.17%(刨花板)、44.00%(指接板)和18.52%(细木工板);另外,采用胶结合连接的人造板-石膏板箱框结构能够保持良好的隔声性能。这能为人造板在室内空间的应用和室内环境优化提供科学依据。

As one of the important materials for interior decoration,wood-based board will have an important impact on the acoustic environment of indoor spaces.It is of great significance to study the sound insulation performance of wood-based panels in indoor spaces.Based on this,the sound insulation performance of wood-based board veneer structure,box frame structure,and box frame structure with gypsum board as the backboard was analyzed in this study.The findings indicate that the plate type has a substantial impact on the acoustic insulation performance.In veneer structure,plywood has better sound insulation performance than other plates.The box frame structure has the potential to greatly enhance the sound insulation performance of the veneer structure.The sound insulation of the box frame structure made of five wood-based boards increased by 30.77%(MDF),7.14%(plywood),29.17%(particleboard),44.00%(fingerboard),and 18.52%(blockboard),respectively.In addition,the wood-based board-plasterboard box frame structure connected by glue bonding can maintain good sound insulation performance.This research can provide a scientific basis for the application of wood-based panels in indoor spaces and the optimization of indoor environments.
