As an important facter in reducing car interior noise, the sound quality of gear noise, particularly the steady sound generated from transmission gears is of increasing importance. With the objective of reducing the source of gear noise, in the past, we presented a simplified method for evaluating gear noise with an eye on transmission error between gears, Through this method. elements influencing noise. such as the gear contact ratio and teeth error. were made clear, Now, this paper describes measurement on noise generated from five gears based on different de5ign criteria. These observations were conducted using a back-to-back gear tester in a semi-anechoic chamber. Gear noise was appraised through the size of the amplitude components in tran5mission error using the above mentioned simplified evaluation method. Thus, the effectiveness of this method was confirmed.
