Abstract

Active-noise-reduction (ANR) headsets protect the hearing of their users from loud persistent noises, such as airplane engines and construction equipment. These headsets generally include ear speakers and special circuitry to cancel or suppress certain types of loud persistent noises. One problem the present inventor recognized with active headsets, particularly those manufactured in mass quantities, concerns the performance variations that stem from inevitable variations in the fit of their earcups against heads of their users. For example, in putting on and taking off these headsets, some users experience low-pitched noises. Accordingly, the inventor devised, among other things, headsets that include front-cavity vents for equalizing the pressure between a front cavity portion of an earcup and an ambient environment.
