Description: Wood boring organisms such as shipworms and gribbles make characteristic sounds as they actively bore into wood. In the laboratory these sounds isolated from ambient noise have been recorded and analyzed. In harbor areas, infested piles and seawalls are usually covered with fouling growth such as barnacles, and the noise created by feeding barnacles and other foulers make it impossible to detect the soft low intensity sounds of wood borers.
