Sound dampening coating can be applied to outside of chute to minimize noise emitted by the chute. Further sound protection is provided by applying a “wrap” insulation to the exterior of the chute. The floor frames of the chute are typically equipped with sound isolator pads at each floor connection point to isolate the chute from the floor of the structure.
