FIELD: acoustics.
SUBSTANCE: headphones comprise a microphone for reducing the vibration in the microphone signal and a vibration sensor, wherein the microphone is configured to receive a first signal including a voice signal, and a first vibration signal, the vibration sensor is configured to receive a second vibration signal, wherein the volume of the cavity of the vibration sensor is configured so that the amplitude-frequency response of the vibration sensor relative to the second vibration signal matches the amplitude-frequency response of the microphone relative to the first vibration signal, and/or the phase-frequency response of the vibration sensor relative to the second vibration signal matches the phase-frequency response of the microphone relative to the first vibration signal; both the microphone and the vibration sensor are configured so that the first vibration signal can be compensated by means of the second vibration signal.
EFFECT: increase in the sound quality.
