Devise helps reduce hospital noise

In school, it was a good old fashioned "shush" that reminded us to keep our voices down. Now an American hospital has taken this a step further by installing a visual reminder to promote a quieter environment for patients in the hospital. This noise-detection device resembles a traffic light positioned near a busy nurses' station. A green light means the noise volume is within a reasonable range. A flashing yellow light warns that the noise is increasing, and a red light indicates the noise level is too loud.
