<p>The application relates to a hearing protection earplug comprising a shell (1000) for being worn at least in part in the ear canal of a user, the shell (1000) having a sound passage (1016,1036) extending from an outer sound inlet opening (1032) of the shell (1000) to an inner sound output opening (1034) adapted to acoustically connect to the user's ear canal, and a noise attenuation button (1002) which is provided at the outer end of the shell (1000), wherein said button (1002) is manually movable relative to the shell between a resting position in which the outer sound inlet opening (1032) of the shell is closed by the button and at least one communication position in which the outer sound inlet opening (1032) of the shell is at least partially opened by the button (1002) for enabling sound communication between the environment and the sound passage (1016,1036) of the shell, wherein the sound passage (1016,1036) is designed such that it has a sound attenuation of less than 10 dB averaged over the audible frequencies. The application also relates to a use of such an earplug and a method for manufacturing such an earplug.</p> |
