Abstract: By monitoring the noise from working location with tea refinement processing equipments and the factory boundary, the difference was compared. Results showed that, the qualified percentage on the noise from working operations and the factory boundary of the new style tea refinement processing workshop is 100% in the daytime and at night. The qualified percentage on the noise from working operations of the old style tea refinement processing workshop is 33.3%, and the noise from the factory boundary in the daytime is 81.25%, and that at night is 62.5%.
