Abstract (en)
[origin: EP2518724A1] The headset has a physiological sensor (18) provided in an insulating cushion of a closed shell of one of earpieces. A microphone set has front and rear microphones (20, 22) placed on the shell and aligned to form a linear array in a main direction toward a mouth of a wearer. A combiner-and-phase shifter (56) reduces non-frequency noise of speech signal and includes a combiner for applying a delay to a signal delivered by the microphone and subtracting a signal delivered by another microphone from the delay signal so as to remove noise from a near speech signal uttered by the wearer.
