Simulation Analysis of Sound Insulation for Urban Traffic Noise

Abstract:

The sound barrier is one of the effective and economical engineering facilities to control the urban traffic noise. The characteristics of urban traffic noise are analyzed both in time-domain and frequency-domain. Then the noise reduction theory of sound barrier is introduced in detail. The determination of the influence factors in insertion loss is researched emphatically. The main procedure of the acoustics design of sound barrier is also systematically studied. According to the main design process of the acoustics design of sound barrier, simulation confirmation is conducted by acoustics software to confirm the noise reduction performance of the barrier.
