clacks
Abrupt knocking sounds
Clacks is the plural of clack—a sharp, abrupt sound like hard objects striking together: the clacks of typewriter keys, the clacks of heels on tile.
The word imitates the sound it describes.
Clack also refers to rapid, thoughtless talk, though this use is dated: the endless clacks of gossip.
