    摘要： A binaural telepresence system includes two communication devices, and two sets of active noise reducing headphones having an active noisecancelling mode and an active hearthrough mode, coupled to the respective communication devices and configured to provide left and right feedforward microphone signals to the communication devices. The first communication device is configured to transmit the first left and right feedforward microphone signals to the second communication device. The second communication device is configured to provide the first left and right feedforward microphone signals to the second set of headphones. The second set of headphones are configured to activate their noisecancelling mode while filtering the first left and right feedforward microphone signals so that a user of the second set of headphones hears ambient noise from the environment of the first set of headphones, so that the user hears the ambient noise from the first set of headphones with ambient naturalness.

    摘要： An ear cup with a microphone apparatus including an inner cup portion, for forming a noise damping space, and an outer cup portion for forming a space for accommodating electronics and/or a current source. The inner cup portion and the outer cup portion are separated by a partition. The inner cup portion has a pocket and two opposingly located recesses in which a bracket for a microphone is disposed. Over the microphone, a windshield is provided, this protecting the microphone from being damaged and also damping wind noise. The windshield has an outer configuration that may be seen as a continuation of the outer cup portion, in order to prevent turbulence in the region of the windshield. The windshield is produced from a porous material, which is surrounded by a mounting frame having nap catches for engagement in snap catches.

    摘要： The present disclosure relates to a height adjustment arrangement (100) for an ear cup in a hearing protector unit, wherein the height adjustment arrangement (100) comprises an elongated member (130) and a tubular holding member (110) connected to the elongated member, wherein the holding member provides a substantially hollow interior (111). The height adjustment arrangement further comprises a clamping member (120), wherein the clamping member is arranged to be moved from an unlocked position, in which position relative movement between the elongated member (130) and the holding member (110) is enabled, to a locking position, in which position relative movement between the elongated member and the holding member is prevented. The holding member (110) comprises a first locking member (114), wherein the second end of the holding member is provided with two flanges (115a, 115b) tapering in a direction towards the clamping member, and wherein the first locking member and the flanges are axially separated. The clamping member comprises a hollow interior with a tapering part, which tapers in a direction away from the holding member, and a second locking member, wherein the tapering part and the second locking member are axially separated.

    摘要： An ear muff style ear protector device having a body for permitting positioning on a wearer's head, and two ear muff ear protectors connected with the body, so the ear protectors can be operatively held relative to a wearer's ears. At least one ear protector can be adapted to selectively enable the wearer to temporarily reduce the level of sound protection to the respective ear to enable external sounds to be heard more clearly. In an embodiment the body is an eye protector assembly, which is connected to the two ear muff ear protectors.

    摘要： An earmuff assembly with a double-shell structure is disclosed for use with a sound-attenuating circumaural headset. The earmuff assembly comprises a cup-shaped outer shell mounted on a resilient outer sealing ring and a cup-shaped inner shell mounted on a resilient inner sealing ring. By means of the two sealing rings the outer and the inner shells are brought into abutment with the head surface around an ear of a wearer. Both shells are structurally rigid. The sound attenuation performance is maximized by isolating the inner shell from the outer shell. The two sealing rings are interconnected through a thin skin layer of soft compliant materials, which acts as a vibration isolating/decoupling means between the outer shell and the inner shell.
