Design culture is tentatively embracing the acoustic conditions and auditory awareness of spaces and objects, thus creating new opportunities for spatial sound practitioners. This thesis examines the making of seven spatial sound design projects in diverse milieux and an eighth project - the establishment of an electroacoustic studio within a school of architecture and design. The projects and the studio are considered models for the ways in which electroacoustic practices might advance the auditory spatial awareness of students and researchers in the academy, and the general community through an interlocking program of teaching, research and events. The creation of the projects and establishment of the studios also articulate a transformation in my own practice from composer to design researcher. Five of the projects are intended to engender in listeners a greater awareness of the acoustic environment and the auditory spatial qualities of those environments, whi ch listeners daily inhabit. Supporting these project studies is a discussion on issues and conditions of making and materials to elucidate my approach to creating spatial sound designs in diverse milieux. Two of the projects investigated the auditory spatial awareness of different communities in Melbourne, with the view of establishing ideas about the auditory culture and the actual environments of that experience. The final project is a facility to house a community of practitioners who aspire to privilege the auditory design and experience of space, through a series of research, teaching and performance activities. While evaluating just how my practice transformed over the course of the projects, I also propose that the combination of the Studio's main elements is critical to the advancement of sound-based research and design as a design discipline. Note to audio and visual materials - This thesis was accompanied by a custom-built multi-channel sound playback environment using Max/MSP and Flash.
