The thesis uses dimension analytical method to work out the similitude rule of noise barriers lab model test, via which noise barriers insertion loss can be measured. The comparison between the result of model test and that of engineering formula prediction indicates that the relationship in terms of acoustic characteristics between the model and the original object can be described in quantity by similitude rule.This conclusion has important value in the acoustic design of noise barriers.
