摘要： Earplugs are formed by extruding an elastomeric material (12) forwardly (F) through an extrusion head (14) so a forward portion of the extrusion enters a shaping cavity (50A). The forward portion of the extrusion is severed from the rest of the mass being extruded to form a globule. The globule is allowed or forced to expand in the cavity, or the cavity is formed of parts that compress the globule, to shape the globule to the shape of the cavity.

摘要： An earplug (10) with a body front portion (22) for insertion into a person's ear canal, has a pocket (30) to increase comfort and is constructed to enhance noise attenuation. The pocket, which allows easier compression of the body front portion for increased comfort, has a plurality of baffles (50) that attenuate sound better than a pocket without baffles. The pocket with baffles is formed by a core pin (80) that lies in an injection mold (82) and that forms the pocket, the core pin having a plurality of slots (81) that form the baffles. The pocket includes a rear portion (36) that forms a wide passage, and the earplug includes a blocker portion (90) that partially or completely closes off the rear pocket passage.

摘要： The present invention relates to a cap (11) intended for use as hearing protection and adapted to enclose the external ear of a user, characterised by at least one vibration-damping weight element (18; 38a-b) of the cap (11), which weight element is arranged so as to at least partly block an audio mode of vibration that would have existed in the cap in the absence of said weight element (18; 38a-b). The invention also relates to a method of producing such a cap, and use of the same.

摘要： An earplug (10) that includes a soft foam body (12) and a stiffener (14) in the body, is produced by a method that has minimum steps and that results in an earplug of attractive design and that uses a minimum of material. One method includes molding an earplug body in a body cavity (52) while a mandrel (56) lies in the body cavity. After the foam material in the body cavity has at least partially solidified, the mandrel is removed, leaving an empty stiffener cavity (60) in the foam body (12). With the body remaining in the body mold (54), flowable stiffener material (14A) is poured into the stiffener cavity of the body and allowed to solidify, to produce an earplug with a molded-in stiffener (14). Another method, results in an earplug (90) with a stem (95) having a rearwardly-projecting stem portion (96). This method includes molding a stem rear portion (96) in a stiffener cavity (110) while allowing stiffener material to project forward of the rear portion to form a stem free front portion (120). The free front portion is projected into a body cavity (104) while foam material in the body cavity is still plastically deformable.

摘要： An earmuff ( 3 ) includes a disc-shaped elastomeric pressure-equalizing element ( 6 ) that lies between an inner end of a cup ( 4 ) and an outer face of an annular element ( 7 ). The elastomeric element ( 6 ) is found to provide a more consistent blocking of environmental sound. The cup inner end has a radial projection 15 that projects into a recess 19 , and the elastomeric element is bent to lie between the projection and the walls of the recess.
