AUDIBLE PEDESTRIAN TRAFFIC SIGNALS: PART 3. DETECTABILITY
This paper, the last of 3 companion papers in this journal, describes the detectability of the sounds emitted by the Nagoya/Traconex audible traffic signal, the unit most commonly found in the western U.S., and especially so in California. Three groups of subjects with normal hearing--young sighted adults (controls), elderly sighted adults, and elderly blind adults--participated in an audiological study. Auditory stimuli, consisting of audible pedestrian traffic signal sounds embedded in various levels of interfering traffic noise, were presented to subjects seated inside a double-walled sound-treated chamber. The subjects' speed of response to the auditory stimuli indicated how quickly a pedestrian might begin to cross the intersection upon hearing the audible pedestrian traffic signal.
