All of the APS devices include a microphone to measure sound and adjust the volume of the APS devices to respond to the ambient sound. Many of the APS devices include a microphone in the pushbutton housing, but some have a separate microphone that may be mounted in the pedestrian signal head or on a signal pole. If the microphone is mounted too far away from intersection and the crosswalk, it will not adequately sample ambient sound where pedestrian is waiting and the resulting tones may be too quiet or too loud.
