Abstract
A vehicle and a controlling method thereof are disclosed. The vehicle includes a first seat in which a talker is seated; a second seat in which a passenger is seated; a plurality of speakers provided in the first seat and the second seat; a microphone for receiving the voice of the passenger or the voice of the talker; and a controller configured to control the speaker to output a masking sound tuned based on the voice of the talker or the voice of the passenger.
Claims18
A vehicle comprising,
- a first seat in which a first person is seated;
- a second seat in which a second person is seated;
- a plurality of speakers provided around or in the first seat and the second seat;
- a microphone configured to receive the first person's voice;
- and
- a controller configured to control the plurality of speakers to output a masking sound tuned based on the first person's voice and control auto gain control sensitivity of the microphone based on the masking sound so that the microphone reduces a received additional voice,
- wherein the controller is further configured to tune the masking sound such that the masking sound is delayed output alternately for a predetermined time in the plurality of speakers, generate asymmetrically an output waveform of the masking sound, and control simultaneously to gradually reduce the volume of the masking sound output for a predetermined time.
A method of controlling a vehicle, comprising;
- receiving voice of a first one of persons seating in the vehicle by a microphone;
- controlling a plurality of speakers to output a masking sound tuned based on the first person's voice by a controller;
- and
- controlling auto gain control sensitivity of the microphone based on the masking sound so that the microphone amplifies or reduces a received additional voice,
- wherein the controlling of the plurality of speakers includes tuning the masking sound such that the masking sound is delayed output alternately for a predetermined time in the plurality of speakers, generating asymmetrically an output waveform of the masking sound, and controlling simultaneously to gradually reduce the volume of the masking sound output for a predetermined time.
