This presentation outlines a new project that offers a novel methodology for the development of new styles of acoustically optimised auditoria and room shape based on biometric sensing and evolutionary computation.
The work is based on established research in emotion and electrodermal activity. If emotional response to sound, space and music can be sufficiently detected in a listener, then it can be used as a fitness function in an interactive evolutionary process. Such a process can be used to generate evolving phenomena or as in this case, to optimise the early reflection sequence of auditoria, that is the surface reflections that occur within 80ms of a sounds propagation.
Optimising early reflections spatially, in distance, azimuth and elevation allows us to develop a unique architectural shell that is developed purely on the relationship between sound, space and the listener.
Listeners are seated in a 2nd order ambisonic sound lab, with biometric sensors (electrodermal activity) picking up an ‘emotional response’ to music and space. The ‘space’ that is being listened to is set up in IRCAM’s SPAT software, and is adaptive and evolving, and responding to the listeners emotional response. The output of the adaptive SPAT environment is driving parametric data in a Grasshopper model generating an architectural form wholly based on the unconscious response of the listener to the music and the evolving space.
The presentation will outline the processes involved and discuss and present the results of tests undertaken in 2021.
