Abstract

The invention relates to a database based complete vehicle noise detection learning device, which comprises a noise collection device, a storage and processing device and a noise output device, wherein the noise collection device selects a recording unit according to different types of noise to record the sound, and carries out standardized setting on the recording position, recording mode and parameters to form a corresponding recording file; the storage and processing device is connected with the noise collection device, carries out format conversion on the recording file to obtain an all-noise audio file, stores the all-noise audio file, carries out filtering processing and format conversion on the recording file at the same time to obtain a characteristic noise audio file and stores the characteristic noise audio file; and the noise output device is connected with the storage and processing device, restores the audio of the characteristic noise audio file and outputs.

Description

technical field [0001] The invention relates to a noise detection and learning device, in particular to a database-based complete vehicle noise detection and learning device for vehicle manufacturers to perform data detection and learning on vehicle noise and other quality problems. Background technique [0002] As an important part of vehicle quality, vehicle noise is attracting more and more consumers' attention. The noise of the whole vehicle refers to the bad sound and vibration generated when the vehicle is stationary or during driving, and affects the central nervous system of passengers to reduce comfort and safety. These noises come from engine, tire noise, wind vibration, air leakage, poor fixing and various vibrations, etc., which have always been the technical difficulties that various car brands are committed to solving. Timely solving the noise problems discovered has become an important link to ensure the quality of the whole vehicle. Therefore, it is very imp...
