In 2022, we had the opportunity to collaborate on an innovative project with the University of Ferrara and the University of Bologna, exploring the impact of sound on sleep. The project, supported by the startup Hi-Interiors and a grant from the Municipality of Milan, aimed to identify the most scientifically effective soundscapes for relaxation and sleep induction.
The project brought together our studio with sound engineering professor Nicola Prodi from the University of Ferrara and psychophysiologists Miranda Occhionero and Andrea Tallarico from the University of Bologna, combining expertise in acoustics, neuroscience, and psychology. Our role as the creative counterpart was to develop a series of soundscapes that the universities could rigorously test in controlled environments.
We began by designing 20 unique, 30-second sound samples, each crafted with attention to how different auditory elements influence the mind and body. These initial samples underwent preliminary testing in the anechoic chamber at the University of Ferrara, where volunteers provided feedback on their emotional and sensory responses. Based on these insights, the most promising soundscapes were refined for further evaluation.
The next phase of testing took place in a controlled sleep laboratory at the University of Bologna. Here, five selected soundscapes were extended to 30-minute compositions and tested on volunteers attempting to fall asleep. In the meantime, their neural responses were closely monitored to assess the physiological effects of each sound. This rigorous scientific approach allowed researchers to determine which soundscape was most effective in promoting deep relaxation and had, in general, the most soothing physiological impact. Ultimately, one soundscape stood out for its ability to induce deep relaxation, highlighting its potential practical applications in aiding sleep.
This collaboration demonstrated the importance of merging creative talent with scientific expertise, making interdisciplinary research an important element for innovative studies that can drive change. The findings have contributed to the research connecting sound and mind relaxation, advancing insights on the potential of sound-based interventions for improving rest and well-being.
