| Outline of Final Research Achievements |
For people with visual impairment, the environmental sound and the room acoustics are information sources showing the situation of the field. Also, auditory signal from acoustic welfare equipment are important. Since the establishment of the new law barrier-free of Japan, the number of guidance systems using sounds in public places has increased. On the other hand, there are also complaints by sighted people against them. As a result, the sound pressure level of the acoustic assistive devices may be excessively reduced or stopped.
In this research, we conducted a recognition survey on acoustic welfare equipment, proposal of environmentally harmonized sign sound, and developed documents of architectural design method for a Easy-to-hear environment. We resolved the conflict between sighted and visually impaired people and derived the viewpoint necessary for coexistence of both.
