| 20120102629 | HEARING PROTECTION SYSTEM FOR USE WITHIN A HELMET - An ear seal assembly comprises a front panel, an outer panel, a hidden panel, a rear panel, and an acoustic transparent fabric inner panel, wherein a front edge of the acoustic transparent fabric inner panel is positioned at a right angle along an inside circumference of the front panel and a rear edge of the acoustic transparent fabric inner panel is positioned at a right angle along an inside circumference of the hidden panel. | 05-03-2012 |
| 20110038496 | HEARING ENHANCEMENT SYSTEM AND COMPONENTS THEREOF - A circuit includes a microphone circuit, an audio processing module, a digital audio processing module, and an active noise reduction (ANR) circuit. The microphone circuit receives acoustic vibrations and generates an audio signal therefrom. The audio processing module generates a representation of the audio signal. The digital audio processing module compensates the representation of the audio signal based on hearing compensation data to produce a hearing compensated audio signal. The ANR circuit receives the hearing compensated audio signal and an ANR signal. The ANR circuit further functions to adjust the hearing compensated audio signal based on the ANR signal to produce an output audio signal, wherein the ANR signal is generated based on the output audio signal. | 02-17-2011 |
