An earmuffs system for noise reduction including an external microphone used in combination with active noise cancellation technology for the reduction of wind or other noises typically experienced while riding a vehicle such as a motorcycle, snow machine or ATV, the earmuffs system including a first earmuff including a first speaker and a first microphone therein; a second earmuff electrically coupled to the first ear muff, the second ear muff including a second speaker and a second microphone therein; noise cancellation circuitry for receiving first sounds from the first microphone and the second microphone and processing the first sounds by in part canceling the first sounds to form a first sound output that is provided from the first speaker and the second speaker; a third microphone placed external to the first earmuff, the third microphone supplying second sounds for the first speaker to output as a second sound output without the second sounds undergoing noise cancellation processing; and a fourth microphone placed external to the second earmuff, the fourth microphone supplying third sounds for the second speaker to output as a third sound output without the third sounds undergoing noise cancellation processing.

A hearing protection device has a base (11) configured for connecting to a lateral portion of a protective helmet (1), an ear cup (20) configured for covering an ear of a user, and a support (30) connecting the ear cup (20) to the base (11). The support (30) has a first arm (31) and a second arm (32) each having an upper part connected to the base (11) by at least one connection member (50) and a lower part connected to the ear cup (20). The at least one connection member (50) is elastically deformable to allow relative movement of the upper part of the first arm (31) relative to the upper part of the second arm (32). The hearing protection device is movable between an active position, in which the ear cup (20) is configured to cover the ear of the user, and an inactive position, in which the ear cup (20) is configured to be spaced apart from the ear of the user.

Implementations of a ballistic helmet having an integrated electronic circuit are provided. An example ballistic helmet includes: a first armor plate attached by a hinge to a first side of the ballistic helmet, the first amor plate is configured and positioned to provide ballistic protection; a second armor plate attached by a hinge to a second side of the ballistic helmet, the second armor plate is configured and positioned to provide ballistic protection; and an integrated electronic circuit configured to operate and power electronic devices conductively coupled thereto.

There is provided a wind noise reduction apparatus that has a simple structure to suppress vibration caused by an air current generated in the course of protection against the wind, while not reducing ambient sound. A wind noise reduction apparatus 1 includes a windshield portion 2 having a first surface 21 that is defined by four sides of a front end 23, a rear end 24, an upper end 25 and a lower end 26 and that is arranged to face an ear front surface and a second surface 22 that is arranged on an opposite side to the first surface; one or multiple support portions 3 stood upright from the first surface 21 of the windshield portion 2; and a catching portion 4 including an insertion hole or insertion opening 44 that is used to hold a chin strap B of a helmet and that is located between a front edge and a rear edge 33 of the support portion 3. The windshield portion 2 is supported by a three or more supporting point structure of the front end 23 of the windshield portion 2 and the support portion 3.

A safety hat assembly for enhancing safety and comfort of a user includes a hat that is selectively sizable to a head of a user and which has a brim coupled thereto. The hat is positionable on the head of the user with the brim extending over a forehead of the user. A pair of safety glasses is slidably engaged to the hat and is selectively positionable in a stowed configuration within the hat and a deployed configuration to protect eyes of the user. An earplug is engaged to and selectively extendible from the hat to allow insertion into a respective ear canal of the user to protect hearing of the user. A set of pads is engaged to and positioned within the hat to cushion the head of the user.

A modular respiratory protection system comprises a frame defining an opening configured to expose a portion of a user's head. A blower is configured to draw air through an air filter and through a portion of the frame. A head protection element is releasably coupled to the frame and the head protection element is configured to cover the opening.

A hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a “bulge” or protrusion over the ear.

Implementations of a ballistic helmet are provided. The ballistic helmet comprises two armor plates, each armor plate can be positioned to cover an ear of a wearer and thereby provide ballistic protection. In some implementations, the ballistic helmet may further comprise two earcup adapters, each earcup adapter is configured to be mounted on an interior side of an armor plate and to allow an attached earcup to rotate thereon. In this way, each earcup may be comfortably positioned over an ear of the wearer and thereby attenuate sound.

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.

Systems for reducing the decibel levels of sound originated external to a sports protective helmet may minimize deleterious effects to the hearing of the individual wearing the sports protective helmet. Through use of a sound reducing object, whether placed in the interior of the sports protective helmet or external to the sports protective helmet, decibel volumes may be reduced across key frequencies that reach human ears while still allowing a player to hear. The result is substantial reduction in hearing loss related to sporting activities.
