| Abstract: | This article indicates that after damping treatment of the cover board of the power aperture on the gear box of the BC131 light truck, noise can be reduced by some 3.2dB sound power level. The article consists of three parts: 1. Mechanism of vibration and noise reduction of the damping structure; 2. Experimental devices; 3. Measurement and calculation of sound pressure level and sound power level. |
