First of all, it needs to be clear that the buffer block is not a silencer. It is not like the "reduction of 80% noise" and "40% reduction of noise" promoted by some businesses. Those statements are obviously not scientific and comprehensive. However, it is necessary to agree that the buffer block can indeed reduce noise to some extent (depending on the specific situation). For example: when some vehicles are loading heavy objects or driving on rough roads, the sound of friction and collision often occurs in the suspension system and the surrounding location. When the buffer block is installed, such problems are solved, and some noise in the surroundings is relatively absorbed. Or more simply, since the bumper block improves the smoothness and comfort of driving, then some of the original related noise will naturally be slightly reduced.
