Problems solved by technology

The resulting microphone signal improves the signal-to-noise ratio (SNR) due to less noise interference, but in some cases ambient noise may leak into the ear through the earpiece and, due to frequency distortion in the propagation path of the speech signal , voice sounds muffled or even hard to hear

Abstract

A method and a device are provided for enhancing microphone signals transmitted from an earpiece of a headset. The method comprises: receiving a first signal and a second signal from an in-ear microphone and an outside microphone, respectively. The in-ear microphone is positioned at a proximal side of the earpiece with respect to an ear canal of a user, and the outside microphone is positioned ata distal side of the earpiece with respect to the ear canal. The method further comprises: digitally filtering out in-ear noise from the first signal using the second signal as a reference to therebyproduce a de-noised signal. The method and the device for enhancing microphone signals transmitted from an earpiece of a headset have the advantage that the sound quality of the microphone signals transmitted from an in-ear microphone can be significantly enhanced.

Description

technical field [0001] The present invention relates to enhancing a microphone signal sent from a headset comprising at least one in-ear microphone and an external microphone. Background technique [0002] A typical headset is a combination of a microphone and earphone speakers for both ears. The microphone is usually housed in a tubular structure close to the user's mouth to receive the user's voice signal. When the voice signal comes out of the user's mouth and travels through the air into the microphone, the signal quality is degraded by ambient noise as the microphone is exposed to the outside environment. [0003] Some advanced headsets incorporate a microphone as part of the earpiece (earpiece) to cover or fit the user's ears. The earpiece forms a seal that blocks ambient noise from entering the ear and allows the microphone to pick up the user's voice directly from the user's ear. The resulting microphone signal improves the signal-to-noise ratio (SNR) due to less ...
