[0033] Example 1:
[0034] like figure 1 , image 3 with Figure 4 As shown, the present invention discloses a car noise reduction structure and a noise reduction method, including the car body, the wheel position of the car body, and the vibration sensor 2 is fixed, and there are four cars outside the car body. 1, car body interior Fixed a plurality of car microphones 3, four car outer microphones 1 are connected in series, and the four vibration sensors 2 are connected in series, and the car host 4 is connected, and the car microphone 3 is connected to the power amplifier 5;
[0035] The noise reduction method adopted by the car noise reduction structure contains the following steps:
[0036] Step 1: Collect the outer wind noise data by the car outside the microphone 1, collect the tire vibration and acceleration data by vibration sensor 2;
[0037] Step 2: Code calculation processing for the acquired data to obtain the corresponding time period waveform;
[0038] Step 3: Based on...
