Acoustemological Investigation: Sound Diary #Tehran is a research-based project that is being developed as part of my ongoing Ph.D. research. This is accomplished by employing sensory methodology as a research tool for observing and analysing architecture and urban design. Art and architecture have always seemed to me to have the potential for social change and the improvement of the existing social order. They can be emancipatory, assisting in self-development, promoting social justice, and even, in small ways, changing the world we live in.
