While the RTB button is what people will interact with the most, it is the acoustic unit which sets the RTB system apart from all the others. The Kombi-S unit houses the electronics that will operate the button and communicate with the controller cabinet as well as provides the auditory signals that make crossing the street safer. The Kombi-S Units provide both the beacon tone that allows those with signt loss to locate the pole and the tones to indicate a walk signal. RTB incorporates the philosophy that audible pedestrian signals should not be blocked. Researh has shown that there is a 5dB reduction in sound if there is even a single person in front of a button level acoustic device. This is why RTB will only install the Acoustic Unit above the pedestrians so that the signals can he heard.
RTB’s acoustic units will make automatic adjustment of the volume based on ambient noise levels. More importantly, you can adjust sound alignment according to street width and buildings in the area. Following the installation, the hand held remote control offers flexible configuration options for each and every crosswalk. There are many customizable features, such as switching the transmitter off at certain times of day or reducing the volume at night. Each RTB Acoustic Unit utilizes 3 individual speakers which allows you to shape the eminating sound so that more sound is directed at the crosswalk and less sound is affecting the neighbours. |
