Abstract: A noise attenuator for reducing clicking and slamming noises produced by the closing of a door includes a thin elongated rectangularly-shaped flexible, resiliently deformable padding member having D-shaped elastic strap loops protruding from opposite short vertical edges of the padding member. One of the strap loops is stretched to fit over a first door knob to thereby hang the attenuator from a first door knob preparatory to use. The padding member is pivoted to a horizontal use position over the door latch and the second loop stretched to fit over the second door knob. When the door is closed, the padding member prevents contact between metal parts of the door and door casing latching mechanism and prevents slamming contact between the door and members in the door casing.
