Abstract
This paper considers the impact on local residents of audible pedestrian signals (APS) that provide cues to the visually handicapped pedestrians on the onset of the various signal phases at a signalized crosswalk. We investigate the extent of the noise intrusion problem of APS through understanding the acceptability by the general public. From the perception surveys conducted, vehicle engine/braking sound, neighbor talking/playing and vehicle alarm are the top three irritating noises experienced while sleeping whereas audible signals is ranked at 21st position. The maximum sound level of the signals found to be acceptable indoors is close to 60 dBA.
