Abstract: A sound control device for a vehicle includes a plurality of speakers in which at least one of the speakers is configured to output a first voice signal, a microphone mounted inside the vehicle and configured to receive a second voice signal generated inside the vehicle, a first processing unit configured to adjust an intelligibility of the first voice signal to generate a third voice signal and adjust an intelligibility of the second voice signal to generate a fourth voice signal, and a second processing unit configured to control the first voice signal and the second voice signal to be output through a first speaker mounted on a first seat and the third voice signal and the fourth voice signal to be output through a second speaker mounted on a second seat.

Abstract: A vehicle sound processing device includes a microphone configured to detect a sound wave signal including a voice signal, a road noise signal, and a media output signal in a vehicle. The vehicle sound processing device also includes a sensor unit installed in the vehicle to measure a vibration signal. The vehicle sound processing device additionally includes a processor configured to determine road surface noise using the voice signal and the vibration signal and determine a first sound wave correction signal by removing the road surface noise from the sound wave signal. The processor is also configured to determine a second sound wave correction signal by removing the media output signal from the first sound wave correction signal using source information of the media output signal.
