Abstract
An aircraft headset includes a headset band, including a head element and a pair of ear cup supports slidably received in the head element, ear cups pivotally attached at one end of each ear cup support; and a microphone boom pivotally attached to one of the ear cups; an improved ear cup tensioning mechanism including a tongue extending laterally from each end of the headset band and a conformal tongue receiver located adjacent the other end of each ear cup support; wherein the tongue receiver is conformal with the tongue, and wherein the tongue and the tongue receiver are constructed and arranged to provide near-constant lateral pressure between the ear cups and a wearer's head. An improved ear cup seal includes an outer seal covering formed of urethane-coated expanded vinyl; an inner flexible layer formed of scythed urethane foam; wherein the inner flexible layer has a memory which returns the ear seal to its original configuration when pressure is released therefrom, and wherein the ear cup seal has a variable configuration having its thickest region behind and below a wearer's ear, along the wearer's neck, and having its thinnest region adjacent the front of the wearer's ear along the jaw line. An improved microphone housing includes a hard outer shell having a cavity therein; and sound-absorbing material located inside the outer shell which enclose the microphone element.
