Abstract: An apparatus including a multi-sensor array having a bone conduction microphone, air conduction microphone, signal processor, and speakers; a signal processor that processes vibration signal data and tonal signal data to produce combined data representative of the vocal communication to substantially reduce or eliminate noise; and a method of applying a signals optimized combination algorithm to optimize the output by intelligently combining the outputs from the two different types of sensors for both working in a noisy environment and quiet environment.

Abstract: A protective headgear including an on-ear headset attachable to an inside portion of the protective headgear; a magnetization exhibited that reduces a gap between the compressible foam material of the protective headgear and the on-ear headset; and a method of adjusting the force of the magnetization by a switch adapted to the outer casing of the protective head gear, wherein the switch adjusts the distance between the protective headgear magnet and the on-ear headset magnet.
