• The user's speech picked up by the microphones in the earpiece maybe contaminated by ambient noise.

• The vibration sensor captures the user's speech via bone and tissue?vibrations that is free of acoustic noise but limited to a frequency of 1 kHz.

• Acoustic echoes in the microphone signals and potential "vibration echoes" in the bone conduction signal are cancelled.

• Acoustic and bone-conducted speech signals are cleaned up using noise reduction technology.

• Microphone signals are enhanced with adaptive beamforming technology, which is most efficient at high frequencies, and mixed with the bone conduction signal at low frequencies.

• Intelligent mixing is controlled by the levels and spectra of speech and noise in the acoustic and bone-conducted signals to achieve the best sound quality.
