DOOR HARDWARE NOISE REDUCTION AND EVALUATION
An example exit device includes a mounting assembly configured for mounting to a door, a pushbar movably mounted to the mounting assembly, a latchbolt mounted to the mounting assembly for movement between an extended position and a retracted position, and a rocker lever engaged between the pushbar and the latchbolt such that the pushbar is operable to move the latchbolt between the extended position and the retracted position. The exit device further includes impact dampener mounted to the exit device and configured to dampen impact between a first component of the exit device and a second component of the exit device during movement of the first component relative to the second component.
