Abstract: An ear plug includes a first shelter for extending into an ear canal thereby preventing water from flowing into an inner ear a second shelter for accommodating with the ear canal thereby preventing water from flowing into the ear canal, and a connection portion is narrower than those of the first and second shelters connected between the first and second shelters. The first shelter has a flexible and thin peripheral flange. The second shelter has first and second walls that defines a hollow cylindrical. The first wall of the second shelter is connected with the connection portion. The second shelter and the connection portion are also hollow.

Abstract: An acoustical hearing device is presented, comprising a foam and at least one component which is mechanically bonded to the foam. The mechanical bonding of the component arises during manufacture, wherein the component is placed into a mold cavity as an insert and a foam is formed within the mold so as to allow controlled penetration of the component during foaming. In an exemplary embodiment, the at least one component comprises a stem having a tip at one end, wherein the tip includes at least one opening at least partially extending therethrough. The mechanical bond resulting when the foam extends through the at least one opening.

Abstract: A noise blocking band earplug has a band (12) with outer portions (44, 46) that are bent to prevent the ear-engaging pods (20, 22) from touching the ground, whether placed right-side-up or upside-down on the ground. When the middle region (32) of the band rests on a horizontal surface (64), a band inner end part (70) extends at an upward incline (C) with its outer end forming a second bend (80) so the outer end part (72) extends at a downward incline (D), with the second bend preventing the pods from touching the ground when the earplug is laid upside-down. At the second bend (80), the largely vertical height (J) of the band is increased and its outer surface (102) is made convex to provide pads for more readily pressing the pods against the outside of the ear canals.

Abstract: An arrangement in hearing protection devices, headphones and the like of the type comprising a frame (1) and plugs (2) arranged at both ends of the frame. Each of the plugs is pressed into contact with the orifice of the related auditory meatus and may also partly enter the passage. The frame (1) is provided with means (3) that contact the skull bone at the related ear for the purpose of dampening vibrations in the frame. Those means can be shaped like bent or enlarged portions of the frame adjacent to each end thereof, said portions being arranged, when the device is in use, to be held in pressure contact against the skull bone in the area of the respective ear.
