The friction noise caused by micro vibration such as fretting often takes place in machine element, and preventing or reducing such a noise is important for designers or operators. In this study, the system, which is able to measure and analyse the friction noise under the fretting condition has developed, and the generation of friction noise under the non-lubricated fretting was investigated in air. In addition to the experiment, the vibration analysis was performed by using the model of unity-degree-of-freedom-system which has mass and spring. The results are as follows. 1) The trigger action such the sudden reduction of the coefficient of friction is necessary for the generation of friction noise. 2) The sound level of friction, which means the amplitude of vibration, increases with increasing the sliding velocity. 3) The fretting frequency does not influence on the frequency of vibration which is always 1400Hz in this study. These three tendencies are the same between the results of experiment and that of the vibration analysis.
