This dataset is derived from experiments aimed at evaluating the performance of 3D-printed hybrid acoustic panels designed to improve indoor acoustic environments by combining sound absorption and diffusion. Laboratory experiments conducted in the ZEB Living Lab measured reverberation time (RT60), with the data stored in the file ZEB_living_lab_data.csv. The panels were tested using two different assemblies selected from ten distinct panel designs to assess their acoustic effectiveness. Additionally, field experiments were conducted in an office environment to evaluate user perceptions of acoustic comfort and panel aesthetics. For this purpose, a survey was administered, available in Survey.docx, and participant responses are recorded in Survey_responses.csv.
