Enhancing well-being through low-frequency resonance: a parametric analysis of space geometry

Resonance at low frequencies strongly influences a room's perception of sound, which can enhance or deteriorate the acoustic experience. Previous research showed that low-frequency modes are also linked to the emotional impact of the acoustic environment; this link calls for further understanding of the effect of resonance at low frequencies on sound perception. However, most acoustic software programs adopt geometric-based simulations, which are not accurate at low frequencies. In this project, we adopt wave-based simulations to characterize room modes at low frequencies depending on the room geometry through a parametric analysis. The study outlines the contribution of design elements, such as curves and sub-volumes, in shaping the acoustic environment by manipulating low frequencies.
