Abstract: The present disclosure provides a computer-implemented method for sound masking. The method includes identifying one class among a plurality of classes based on frequency characteristics of a voice of a first occupant in a vehicle, obtaining reference voice data corresponding to the identified class, generating a personalized masking sound for the first occupant by synthesizing the reference voice data with white noise, and controlling an output of the personalized masking sound.

Abstract: A sound control device and a method for controlling the sound control device provided in a vehicle. The method comprises obtaining an input signal including at least one of a reference signal of an accelerometer or an error signal obtained from a sound signal of a microphone; adjusting low frequency components of the input signal based on magnitudes of the low frequency components of the input signal and a preset reference magnitude; generating a noise control signal based on the adjusted input signal; and transmitting the noise control signal so that a speaker outputs the noise control signal.

Abstract: A method and apparatus of controlling a sound using an audio system in a vehicle, includes receiving seat posture information related to a seat by occupied an occupant among seats in a vehicle, determining at least one speaker to output a sound among a plurality of speakers in the vehicle according to the seat posture information, and generating a control signal to control the sound output by the at least one speaker according to the seat posture information.

Abstract: A vehicular belt tactile apparatus is provided. The apparatus includes a buckle, a belt configured to be fastened to the buckle and at least one air pouch disposed at a portion of the belt that contacts the body of an occupant when the belt is fastened to the buckle. An air controller generates a control signal when the belt is fastened to the buckle. The buckle includes an air supply unit that is configured to inject air into the at least one air pouch through the belt or to discharge air from the at least one air pouch in response to the control signal.

Abstract: An active noise control apparatus of vehicles capable of making it difficult for a passenger in a vehicle to hear the voice of another passenger, achieving privacy protection, and a method of controlling the same are disclosed. The active noise control method includes primarily determining a noise level based on a first microphone signal input through a microphone corresponding to a first seat, secondarily determining whether to output an anti-noise signal generated based on the first microphone signal and the magnitude of the anti-noise signal based on the noise level and the level of the first microphone signal, and outputting the anti-noise signal through a headrest speaker of a second seat in response to the secondary determining.

Abstract: A noise shut-off device is provided for doors of an automotive vehicle to effectively prevent driving noises from being introduced to the vehicle interior through draining holes formed at the bottom of the vehicle door, while allowing the draining out of water through the draining holes. The device has an external cylinder member with an open part having a vertical cylindrical opening and a plurality of main capillary ribs protruding outward from the open part, and an internal cylinder member with a shaft part being vertically accommodated in the open part cylindrical opening and having a plurality of auxiliary capillary ribs extending outward from the external circumference of the shaft part.

Abstract: A noise shut-off device for doors of an automotive vehicle to effectively prevent a variety of driving noises from inducing through draining holes formed at the bottom of the door, while the draining holes can also play their function of draining out water, thereby preventing the deterioration of quietness at the internal room of the vehicle caused by driving noises inducing via draining through-holes, the device being fastened with internal and external panels having draining through-holes at the bottom thereof, the device further including: an external cylinder member with an open part being vertically pierced in the cylindrical shape and a plurality of main capillary ribs being deposited at the interval of multi-layers externally protruded all over the external circumference of the open part; and an internal cylinder member with a shaft part being vertically accommodated in the open part of the external cylinder member and a plurality of auxiliary capillary ribs being deposited at the interval of multi-lay
