The research paper titled "Echo-Symbiosis" explores the complex relationship between sound and architecture. It particularly focuses on how acoustic conditions within residential environments can shape and influence human experience and daily life. The term "sound-symbiosis" is used to describe the dynamic collaboration between architectural elements and acoustic phenomena, which together contribute to creating an acoustic atmosphere.

The aim of the research is to understand the living space through sound and acoustic atmosphere, as well as to understand sound as a creator of space, and to connect space with the social context and subjective experience. This is methodologically achieved through three case studies, three examples of residences: 01.A five-member family living in a suburban house in Athens, Greece, with a cat and a dog, 02.Two working students sharing an apartment in the center of Athens with a dog, 03.A 25-year-old Greek woman living alone in an apartment in Lille, France.The soundscapes of these residences are recorded, analysed, and allow for conclusions to be drawn. The complexity of sound-symbioses, their significance, and the necessity of their correlations are proven to be important parameters for a non-ocularcentric, non-quantified, but multisensory architectural design.
