An earplug (20) is provided which allows conversation to be conducted whilst inserted in the ear, and blocks out certain noise without substantially sealing the ear canal, and causing discomfort to the wearer. In one embodiment, the earplug includes a first cylindrical element (28) open at one end (30), having a substantially convex shape at its other end (34) for insertion into the outer ear canal, and a second element (32) which fits into the open end of the first cylindrical element to form a connecting juncture therewith. The first and second elements have air circulation means. |
