Abstract
The study aims to determine the most efficient and likeable type of Accessible Pedestrian Signal sound for students with visual disabilities in the University of the Philippines Diliman. The five most frequently used sound types were considered for the study, which are “Speech message”, “Toks”, “Clicks”, “Cuckoo”, and “Chirp”. The study made use of a functional assessment, through a simulation with twelve (12) participants that measures their reaction and total crossing time. It also made use of a qualitative assessment through a survey patterned after Minoru Sasaki’s Questionnaire on Preference to the Environmental Sounds. Overall, the “Tok” sound is the most suitable Accessible Pedestrian Signal tone for the university. It is perceived to be the most likeable sound, and although it does not produce the fastest reaction and crossing time, it will still be efficient enough to get pedestrians to cross safely within the WALK interval duration of 15 s.
