Decrease Noise Levels for Increased Patient Satisfaction - Utilizing the same design as a traffic light, Yacker Tracker is a unique audio-visual reminder for anyone passing by nursing stations and through lobbies. Designed to bring noise to appropriate levels that improve patient satisfaction, a green light indicates comfortable sound level for resting patients, while a flashing yellow light warns of increased noise. If sounds rise above programmable decibel level, an alarm is activated and the red light is illuminated. Alarms can be changed to a voiced "quiet please" instead of a siren to better suit quiet, healthcare zones.
