The examination of the Sound Diffusion panel provides an opportunity to coordinate the geometry of the precast panel to the manner in which the geometry of the panel might diffuse or absorb sound. Optimized performance for sound abatement is now possible through very precise digital analysis and subsequently it is possible to translate the manner in which a wall or volume might assist in diffusing the sound by the depth, angle, or configuration of the panel surface. Urban noise pollution continues to impact real estate value and will only rise as population density increases. In the application of either façade or mechanically stabilized earth (MSE) panel it is possible to consider how a more calibrated and integrated precast panel might participate in revitalizing real estate zones or protecting buildings programs from unwanted noise pollution. As specific performance criteria emerges, it would be possible to connect height, proximity, duration, and frequency to the parametric model to understand more fully the diffusion and atmospheric capabilities of the geometry. Where necessary, it would also be possible to override pragmatically derived solutions for aesthetic considerations as well.
For the purposes of this research, the Sound Diffusion panel is a single sided mold that utilizes the CNC machine to directly mill the casting surface. In addition to applying a range of densities to the panel, (1 x 1 column vs. 3 x 3 column) it was also a consideration to apply a range of these multi depth panels to a customized surface. In doing this, the panels were stretched to accommodate the new macro geometry and thus created unique and non-repeating panels. To economize the casting process, panels can be ‘ganged’ together and milled and cast as tall columns spanning to a distance of up to 36’-45’. This would then make it consistent with targeted lengths of precast within current standard precast practices.
