  1. 3845. Simulation and Experimental Validation of Sound Transmission Loss in Stone Wool Sandwich Panels (FA2026/875)

    A03 Building Acoustics

    This paper investigates the acoustic performance of stone wool sandwich panels with steel facings at two different thicknesses. Sound transmission loss is predicted using a poroelastic model based on Biot theory, which accounts for the anisotropic structure of stone wool. Three modeling approaches are compared to assess the effect of material parameters: a simplified poroacoustic model using...

  2. 3846. Statistical analysis of sampling strategies for sound insulation verification: A case study (FA2026/878)

    A03 Building Acoustics

    The in-situ verification of airborne and impact sound insulation in buildings relies on acoustic measurements that are necessarily limited in number. In practice, each country defines its own sampling approach based on local construction practices and economic feasibility. Typically, representative rooms are tested instead of the entire building, assuming repetition in architectural layout and...

    A03 Building Acoustics

    In August 2024, construction of Rockwool’s Acoustic Laboratory in Hedehusene, Denmark was completed. The laboratory includes a reverberation chamber and vertical, horizontal, and flanking transmission facilities. The vertical transmission facility is being commissioned to comply with the requirements of ISO 10140. This paper presents the commissioning process, interpretation of standard’s...

  4. 3847. On Statistical Sampling in Standardized Flanking Transmission Measurements (FA2026/635)
    Arne Dijckmans (Buildwise)

    A03 Building Acoustics

    A recurring issue in standardized building acoustic measurements is determining the number of sampling positions required to achieve a prescribed confidence interval. Although measurement uncertainty can be reduced by increasing the number of samples, practical constraints limit the feasible number of excitation and measurement positions. This paper examines the measurement of the velocity...

  5. 3849. Sound attenuation performance of compact multi-resonator silencers for natural ventilation ducts (FA2026/378)
    Takumasa Tsuruha (Takenaka R&D Institute)

    A03 Building Acoustics

    Although natural ventilation apertures are installed on building façades to improve indoor air quality, they reduce the sound insulation performance of the exterior walls. One countermeasure to address this issue is installation of silencers inside the apertures. Such silencers require a compact design that is thinner than the wall thickness. In addition, the silencer should have a simple,...
