Synchronous belt drives combine the advantages of simple belt drives (flat, trapezoidal or ridged) due to their low weight, low maintenance, large linear speed ranges and high transmission ratios with the advantages of chains: absence sliding, synchronized transmission of speed, low tensioning, etc. Thanks to the toothing of the belt which enters the corresponding one of the synchronous pulleys, there is direct transmission of the power without sliding as between two gears. This article develops an experimental study which makes it possible to see the influence of the angular speed, the engine torque and the setting tension on the impact noise of the belt teeth on the pulley teeth during meshing and vibrations of the free strands of the belt. We have measured the noise generated by three transmissions by synchronous belts of type AT10, BAT10 and SFAT10.

同步皮带传动结合了简单皮带传动（扁平、梯形或脊状）的优点，因为它们重量轻、维护成本低、线速度范围大和传动比高，同时具有链条的优点：无滑动、速度同步传输、张力低等。由于带齿进入相应的同步带轮之一，因此可以直接传递动力，而不会像两个齿轮之间那样滑动。本文开展了一项实验研究，可以看到角速度、发动机扭矩和设定张力对皮带齿在啮合过程中对皮带轮齿的冲击噪声和皮带自由股的振动的影响。我们测量了 AT10 型同步带三个传动产生的噪音，
