Abstract: A noise reduction method and apparatus for an on-board environment, an electronic device and a storage medium are provided, which are applicable to a field of computer technology, and particularly to a field of audio processing. The noise reduction method for an on-board environment includes: receiving an interference signal in the on-board environment and receiving a sound signal in the on-board environment, the interference signal comprising a vibration signal of a vehicle; and performing noise reduction processing on the sound signal in the on-board environment to obtain a noise-reduced signal; wherein, the noise reduction processing comprises cancelling the interference signal from the sound signal in the on-board environment.

Abstract: A test system, is provided, which relates to a technical field of detection devices, and particularly to a test system of an artificial intelligence terminal. The test system comprises: a signal shielding box, a test unit, a control terminal and a server; the test unit is disposed in the signal shielding box; a router of the test unit is in wired connection with a to-be-tested terminal; the control terminal is in wired connection with the router; and the server is in wired connection with the router. Through the signal shielding box, the signal transmission between the router and the to-be-tested terminal is effectively shielded from external signals. In addition, due to the wired connections, the stability of the signal transmission is ensured, which solves existing problems of unstable signal transmission and signal crosstalk during signal transmission using wireless transmission technologies.
