A lots of acoustic factors affect noise annoyance. However, in traditional noise control engineering, design of control scheme is usually based on the required reduction of A-weighted sound pressure level rather than the improvement of noise annoyance. In this study, based on the improvement of noise annoyance, a method optimizing noise control schemes was proposed, and this method was applied to the optimization of sound barriers for a substation. Results showed that the same sound barrier had a great different effect on improving noise annoyance of different interested points, and the sound barrier having a better reduction of A-weighted sound pressure level maybe was not the best for improving noise annoyance. Therefore, design of noise control scheme should consider the relative location between noise source and interested sound environmental protection target, and select the best one for improving noise annoyance.
