Abstract
A simulation system and method for simulating a noise environment of a vehicle includes a memory configured to store a reference sample signal and a noise sample signal, a control unit electrically connected to the memory and configured to generate a reference signal based on the reference sample signal, generate a noise signal based on the noise sample signal, and transmit the reference signal to a noise control system, and a speaker electrically connected to the control unit and configured to convert the noise signal into a sound wave and output the sound wave.
Claims13
A simulation system for a noise environment of a vehicle, the simulation system comprising:
- a memory configured to store a reference sample signal and a noise sample signal;
- a control unit electrically connected to the memory and configured to generate a reference signal based on the reference sample signal, generate a noise signal based on the noise sample signal, and transmit the reference signal to a noise control system;
- and
- a speaker electrically connected to the control unit and configured to convert the noise signal into a sound wave and output the sound wave,
- wherein the control unit is configured to adjust the noise signal so that the sound wave matches a sound wave corresponding to the noise sample signal at a collection location of the noise sample signal based on acoustic transfer characteristics between the speaker and the collection location of the noise sample signal.
A method implemented by a simulation system for a noise environment of a vehicle, the method comprising:
- generating, by a control unit, a reference signal based on a pre-stored reference sample signal;
- generating, by the control unit, a noise signal based on a pre-stored noise sample signal;
- transmitting, by the control unit, the reference signal to a noise control system;
- and
- outputting, by the control unit, the noise signal using a speaker that converts an electrical signal of the noise signal into a sound wave,
- wherein the control unit is configured for adjusting the noise signal so that the sound wave at a collection location of the noise sample signal matches a sound wave corresponding to the noise sample signal based on acoustic transfer characteristics between the speaker and the collection location of the noise sample signal.
