Hearing protectors for military purposes were first used by the ancient Greeks. The earplug was patented in 1864. In 1905 work started on designing mechanical devices to limit the damage done by gunfire noise.

Mallock-Armstrong designed these plugs in 1914 called “ear defenders” and they were extensively used in World War 1. The central rod is for removing ear wax from the plugs
