The present disclosure relates to a hearing protection device 10, 10′ for protection in different hearing situations A, B, C. The device 10, 10′ comprises a microphone 30, 30′, 32, 32′, a sound reproduction unit 38 having a loudspeaker 50, 50′, 52, 52′ and a controller 60 for processing an ambient electrical signal. The present disclosure further relates to a controller 60 for such a hearing protection 10, 10′. The present disclosure furthermore relates to a method of switching such a hearing protection device 10, 10′ in different hearing situations A, B, C.

An electronic hearing protection device is provided. The electronic hearing protection device includes an amplifier and a speaker to relay sounds, such as conversations, to the user of the hearing protection. The hearing protection device provides adaptive gunshot recognition and suppression technology.

A hearing protection system is provided. The hearing protection system has a first active hearing protection system. The first active hearing protection system is level-dependent. The hearing protection system also has a second active hearing protection system. The second active hearing protection system is level-dependent. Each of the first and second active hearing protection systems are configured to operate in an independent mode and a dual-protection mode. A dual-protection mode level dependent function of the second active hearing protection system is different than an independent mode level dependent function.

A hearing protection device is provided. The hearing protection device includes a first earmuff connected to a second earmuff by a headband. Each of the first and second earmuffs are configured to dampen ambient sound. The hearing protection device also includes an antenna, located within a housing of the first earmuff. The antenna comprises a rigid portion coupled to a flexible portion. Both the rigid portion and the flexible portion are fixed within the housing. The flexible portion is configured to remain substantially in line with a ground plane with respect to the rigid portion.

According to an aspect of the present disclosure, an ear cup assembly for a hearing protector is provided. In accordance with an example, the ear cup assembly comprises an outer casing, a sealing ring detachably attached on the rim of the outer casing and suitable for sealingly abut against the head of a user around an ear of the user, and a user operable release mechanism for loosening the sealing ring from the outer casing, said release mechanism arranged within the outer casing.

A calibration device and method of manufacturing the same. The calibration device for a hearing earpiece configured to at least partially protrude into the ear canal of a user includes a calibration base. The calibration base a calibration insert. An air chamber is defined between the calibration base and the calibration insert. The calibration device also includes at least one earpiece receiving mechanism defined on the calibration insert. The at least one earpiece receiving mechanism is configured to create an sealed connection between given ear piece and the air chamber for calibration. The earpiece receiving mechanism is configured to at least partially receive the given earpiece. A corresponding method of manufacturing is also included.

Occlusion devices, earpiece devices and methods of forming occlusion devices are provided. An occlusion device is configured to occlude an ear canal. The occlusion device includes an insertion element and at least one expandable element disposed on the insertion element. The expandable element is configured to receive a medium via the insertion element and is configured to expand, responsive to the medium, to contact the ear canal. Physical parameters of the occlusion device are selected to produce a predetermined sound attenuation characteristic over a frequency band, such that sound is attenuated more in a first frequency range of the frequency band than in a second frequency range of the frequency band.

An audio enhanced hearing protection system to be worn by a user includes an ambient noise reduction assembly having a primary noise reduction unit and a secondary noise reduction unit. The audio enhanced hearing protection system also includes an audio input assembly having one or more environmental microphones to receive raw environmental audio signals. The raw audio signals are transformed into processed audio signals via a digital signal processing assembly prior to transmission to a user. The audio enhanced hearing protection system also includes an audio output assembly having at least one speaker to transmit processed audio signals to a user.

Devices, methods, and computer program products are provided herein for hearing safety. An example hearing safety device configured to be worn by a user includes an earmuff body that defines an interior cavity configured to receive the user's ear therein when worn by the user and an exterior surface opposite the interior cavity. The hearing safety device includes an ear lid attached to a surface of the interior cavity. The ear lid projects into the interior cavity from the surface of the interior cavity and defines a sealing surface configured to substantially seal an ear canal of the user's ear when the hearing safety device is worn by the user. The hearing safety device also includes an adjustment mechanism operably attached to the ear lid and configured to move the ear lid relative the interior cavity of the earmuff body.

An acoustic earmuff device comprising a pair of earmuff cup assemblies such that each is configured to be arranged at a location proximate to an ear of an user, wherein each earmuff cup assembly comprises means (320) for adapting a pressure applied to the location proximate to the ear so that the pressure around the ear is evenly distributed and a even seal is achieved, wherein the means for adapting a pressure comprises an adaptive layer (324) that is configured to apply the pressure around the ear evenly regardless whether that location comprises any protruding element (2).
