Problems solved by technology

An audio signal may also be combined with the noise cancelling circuitry in a manner that does not allow the audio signal to be reduced by the system.
Helmets are heavier may cause more undesired fatigue to the user.
Headphones utilizing larger ear-cups that accommodate more noise absorbing material are more difficult to fit inside of a helmet without substantially increasing the size of the helmet.
Headphones utilizing ear-cups that readily fit inside of a helmet may not provide a satisfactory level of passive ambient noise reduction when the headphone is utilized in a helmet being used in extremely loud environment (e.g., military helicopters, military jets, military tanks, military transport vehicles, autoracing etc.).
Conventional noise canceling circuitry and ambient noise absorbing materials within he

Embodiment Construction

[0030]FIG. 1 is a schematic block diagram of an embodiment of a hearing enhancement system 10 that includes a left ear unit, a right ear unit, a left bladder, and a right bladder. Each of the left and right ear units includes an ear-cup and an ear seal.

[0031]Each of the left and right bladders may be included as part of a fully articulating air bladder system. In this configuration, the hearing enhancement system 10 provides improved ambient noise reduction and enables the use of one or more helmet accessories. As such, the hearing enhancement system 10 is well suited for use in extremely noisy environments.

[0032]The left ear unit includes a left ear-cup mechanically coupled to a left ear seal. Similarly, the right ear unit includes a write ear-cup mechanically coupled to a right ear seal. The ear seals may have a torus (e.g., doughnut) shaped structure where an outside pliable material (e.g., plastic, cloth, leather) is filled with a material (e.g., foam, gas, gel, liquid) that com...
