In this paper, the relation of tooth profile errors which have the largest effect on noise among the independent errors of gear and single flank error curve in the rolling gear test was investigated. As a result, the relation of the tooth to tooth composite error and sound pressure level of gear was made clear, and it was also found that single flank error curve is the important data on gear noise. When tooth profile error is small (1st class), aniong 3 fators of gear noise, tooth profile error, revolution and load, revolution gives the largest effect, tooth profile error gives slightly smaller effect and load gives the smallest effect. When tooth profile error is large (3rd class), among 3 factors of gear noise, tooth profile error gives the largest effect, and revolution gives the small effect. Among 3 kinds of tooth profile error, profile concave error at pitch point gives the largest effect on gear noise, profile concave error at tooth flank gives the larger effect and profile concave error at tooth face gives the smallest effect. On the frequency spectrum of gear noise, tooth-contact frequency fz has the highest sound pressure level on the pitch line velocity over 10m/s. 2f_z〜3f_z high frequency has the highest sound pressure level on the low pitch line velocity, and the highest level shifts to 3f_z〜4f_z frequency with the increasing load. In the same tooth profile error, when the load or the revolution increases, the sound pressure level of the high frequency over f_z becomes higher on the revolution over 10 m/s, and the sound pressure level of the low frequency under f_z becomes higher.
