The visually handicapped, mainly the blind, perceive spatial environment by aural clues, such as detection of obstacles, confirmation of direction, judgement of the circumstance and so on. Our study is undertaken for the purpose of establishing an architectural acoustic design for the blind. In the present study, the concrete problems affecting to the perception ability of the blind in the architectural acoustics are extracted and the necessity of those studies is examined through the interview with the visually handicapped. As the results of examination, it is revealed that these studies, characteristics of sounds generated from floors (footfall sound), reverberation in a architectural space and influence of environment noise, are very important for the visually handicapped.
