A safety helmet and accessory system for construction worksites. The system includes a safety helmet that defines two apertures, each aperture being positioned on the helmet so that they will correspond to a user's left and right ears when the safety helmet is placed on the user's head, the safety helmet has a plurality of cord holder attachments attached within an inner circumference of the safety helmet. A pair of capsules, each capsule is secured within each aperture of the safety helmet. A cord that has two terminal ends and each terminal end has a securing device. And, a pair of earplugs that define a stem, the stem of each ear plug has a receiver that receives each securing device. The system provides a safety helmet that has an integral earplug securing system.

Disclosed is a method for manufacturing a generally circular, oval or rectangular sealing ring for an acoustic device, the sealing ring being configured for being in contact with the skin of a user during use. The method includes: forming, in an injection molding step, a covering being generally U-shaped in cross-section; and attaching the end sections of the covering to a support element. The invention also relates to a sealing ring of the above-mentioned type.

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 ballistic helmet comprising a ballistic shell, wherein within the thickness of the ballistic shell, or inside the ballistic shell, there is provided one or more circuit layers forming a circuit, which circuit comprises a power bus and a data bus, and wherein one or more power connections and one or more data connections are provided on the inside and/or on an edge of the ballistic shell for providing power and data to/from one or more electrical devices through the circuit.

A wireform attachment mechanism, or support arm, that can be used to attach an earcup to a helmet. The outer end of the support arm can be opened to release the earcup, or closed to clamp onto the earcup.

Hearing protection device (10, 10, 10) with an indication unit (40a, 40b) and a detection unit (30, 30, 30) to send a first detection signal, to assign a distance value based on a second detection signal of an external device (50, 50) representing the physical distance to the external device (50, 50) and to control the indication unit (40a, 40b) to provide an indication to the user (100) if the assigned distance value is at or below a predetermined threshold distance value. Thus, a collision may easily and reliably be prevented by providing an indication to the user (100), so that the risk of missing relevant sound of a moving person or object is overcome. A collision warning system comprising such a hearing protection device (10, 10, 10) and an external device is also provided. Furthermore, a method of retrofitting a hearing protection device (10) with such a detection unit (30, 30, 30) is provided.
