Research data, simulation models, and analysis code for "Acoustic Performance of Additively Manufactured Building Elements: Influence of Material Selection and Manufacturing Methods on Room Acoustics"

This dataset contains the complete data collection for the impedance tube measurements and room-acoustic simulations reported in the paper “Acoustic Performance of Additively Manufactured Building Elements: Influence of Material Selection and Manufacturing Methods on Room Acoustics.” The dataset is provided in two main archives: AcousticProperties.zip and Pachyderm_Results.zip. AcousticProperties.zip contains folders and files related to the impedance tube measurement data and MATLAB processing outputs. The archive is structured as follows: 0_ImpedenceTube_Measurements TransferMatrix_Data: raw transfer matrix measurement data TransmissionLoss_Data: raw transmission loss measurement data 1_Matlab_Code: MATLAB scripts used to calculate acoustic parameters. These include absorption coefficients, reflection coefficients, transmission loss, and related quantities. 2_Matlab_Output AcousticProperties_CSV: processed acoustic-property data in CSV format AcousticProperties_Plotted: plots generated from the MATLAB analysis The impedance tube measurements cover 134 additively manufactured surfaces. The MATLAB scripts generate category-specific plots and summary graphs. Many of these are included in the associated paper. Pachyderm_Results.zip contains the Rhino/Pachyderm acoustic simulation model, simulation outputs, and post-processing files. The archive includes the following folders: The 3_PachydermModelAndOutput folder within Pachyderm_Results.zip contains the core Pachyderm model and simulation outputs, organized by tested ceiling configuration. Specifically, it includes the following configuration folders: V0_Ceiling_Painted_Concrete V1_Ceiling_Mineral_wool_tiles V2_Ceiling_E3DP-Clay Craggy-Striated - alphaH V3_Ceiling_E3DP-Concrete Rugged-Striated - alphaH V4_Ceiling_Cast-1.1 Pitted-Striated - alphaH V5_Ceiling_Cast-1.2 Gritty - alphaH V6_Ceiling_SCA-1.1 Pitted - alphaH V7_Ceiling_SCA-1.2 Layered - alphaH V8_Ceiling_SCA-2.1 Pitted - alphaH V9_Ceiling_SCA-2.2 Pyramidal - alphaH V10_Ceiling_SC3DP-1.1 Smooth - alphaH V11_Ceiling_SC3DP-1.2 Craggy - alphaH V12_Ceiling_SC3DP-2.1 Smooth - alphaH V13_Ceiling_SC3DP-2.2 Rugose - alphaH V14_Ceiling_SPI-1 Granular - alphaH V15_Ceiling_SPI-2.1 Smooth - alphaH V16-Ceiling_SPI-2.2 Helmholtz - alphaH The Classroom_Acoustic_Boundary_Conditions.xlsx file, located in the root of Pachyderm_Results.zip, contains the acoustic boundary-condition data used in the simulations. 4_Data_Analysis Graphs: Graphical analysis of the Pachyderm simulations CSV: exported simulation data in CSV format PythonScript: Python scripts used to analyze Pachyderm outputs and generate plots This dataset includes all raw data, processing scripts, simulation models, outputs, and plotted figures necessary to reproduce the acoustic-property calculations and analyses presented in the paper.
