The research was targeted on seat positioning motors used in higher category cars. First, noise evaluation method used by the manufacturer during the end-control is investigated and compared with laboratory measurements. In the second part, a complex vibration/noise generation model is set up, possible vibration and noise transfer paths are analyzed and the dominating path identified. In the final part, some modifications made on groups of motors and their noise reduction effect is described. Cumulative application of the most effective changes led to about 6 - 8 dB(A) average noise level reduction.
