In the presented work the sound generation design procedure is presented. On its basis the mathematical model of calculation of the noise emission by a gearbox of cars of family GAZ-3110, 31105 is created. Diagrams of emission of noise by a gearbox depending on frequency of rotation of its entrance shaft and a backlash in gearing of teeths are received. They show, that in case an angular backlash in gearing radiated noise increases by 2-3 dB for each 0.5 degrees. As a result the methodology of the analysis of degree of wear of gearbox’s elements on the basis of noise spectrum should be created. We present the methodology of noise analysis of overmuch action of teeth based on the model of noise emission of elastic plates. According to the developed methodology we got the dependences of the acoustic emission of the gearbox for GAZ vehicle for the whole range of working speed of the engine from different level of wear of gears’ closed pairs. The analysis of the received data showed the increase of the acoustic emission by 1.2-1.5 times at the frequencies corresponding the overmuch action of the gears. This data can be used for analysis of the noise of a car to separate the noise of the gearbox, and also for counting and estimating the possible noise of a car.
