随着人们对建筑声学性能的要求越来越高,准确评价建筑墙体的声学性能已成为一个重要的研究课题。然而,现有的研究主要集中在混凝土等一般建筑材料上,钢铁,和玻璃。对于木结构墙,由于材料本身的吸声性能和结构设计的复杂性,对其声学性能的分析还比较薄弱。此外,缺乏对其频谱特性和声阻抗的定量描述。分析木结构建筑墙体的声学性能,将建筑信息模型(BIM)与阻抗管法相结合,构建了基于BIM技术的建筑墙体性能测试系统。采用阻抗管法,并设计了吸声和隔声性能测试函数。结果表明,在错误测试中,实验组与对照组的误差范围为[0.01,0.18],实验结果具有较高的可靠性。在不同样品在不同声音频率下的隔声计算中,当频率为1600Hz时,对照组和实验组的隔声分别为65.30dB和70.14dB,证明了设计方法的有效性。以上结果证明了BIM技术和阻抗管法在木结构建筑墙体声学性能分析中的实用性。本研究为减少木结构建筑的室内环境,提高人们居住环境的舒适度提供了有力的技术支持。
With the increasing demand for building acoustic performance, accurately evaluating the acoustic performance of building walls has become an important research topic. However, existing research has mostly focused on general building materials such as concrete, iron and steel, and glass. For wooden structure wall, due to the
sound absorption performance of the materials themselves and the complexity of structural design, the analysis of their acoustic performance is still relatively weak. Moreover, there is a lack of quantitative description of their spectral characteristics and acoustic impedance. To analyze the acoustic performance of wooden structure building walls, Building Information Model (BIM) and impedance tube method were integrated to construct a building wall performance testing system with BIM technology. The impedance tube method was applied and testing functions for
sound absorption and insulation performance were designed. The outcomes indicated that in the error test, the error range between the experimental group and the control group was [0.01, 0.18], indicating a high reliability of the experimental results. In the calculation of
sound insulation of different specimens at different
sound frequencies, when the frequency was 1600Hz, the
sound insulation of the control group and experimental group was 65.30dB and 70.14dB, proving the effectiveness of the design method. The above results demonstrate the practicality of integrating BIM technology and impedance tube method in the acoustic performance analysis of wooden structure building walls. This study provides strong technical support for reducing the indoor environment of wooden buildings and improving the comfort of people\'s living environment.
