Abstract
An acoustic control device of a vehicle includes a memory, a processor configured to generate a noise cancelling signal for removing noise generated inside the vehicle, a speaker disposed inside the vehicle and outputting the noise cancelling signal according to control of the processor, a microphone disposed inside the vehicle to detect a sound wave signal, and an acceleration sensor disposed in the vehicle to measure a vibration signal, wherein the processor determines a frequency response based on an acoustic transfer path between the speaker, the microphone, and the acceleration sensor and compares the determined frequency response with a normal frequency response stored in the memory and determines whether the acoustic transfer path is abnormal.
Claims20
An acoustic control device of a vehicle, the acoustic control device comprising:
- a memory;
- a processor operatively connected to the memory and configured to generate a noise cancelling signal for removing noise generated inside the vehicle;
- a speaker disposed inside the vehicle and outputting the noise cancelling signal according to control of the processor;
- a microphone disposed inside the vehicle to detect a sound wave signal;
- and
- an acceleration sensor disposed in the vehicle to measure a vibration signal,
- wherein the processor determines a frequency response based on an acoustic transfer path between the speaker, the microphone, and the acceleration sensor, and compares the determined frequency response with a normal frequency response stored in the memory and determines whether the acoustic transfer path is abnormal according to a result of comparing the determined frequency response with the normal frequency response.
An acoustic control method of a vehicle that is performed by a computing device including one or more processors and a memory storing one or more programs executed by the one or more processors, the acoustic control method comprising:
- determining, by the one or more processors, a frequency response based on an acoustic transfer path between a speaker, a microphone, and an acceleration sensor of the vehicle;
- comparing, by the one or more processors, the determined frequency response with a normal frequency response stored in the memory;
- and
- determining, by the one or more processors, whether the acoustic transfer path is abnormal according to a result of comparing the determined frequency response with the normal frequency response.
