Acoustic Barriers to Reduce Sound Pressure and Environmental Noise in the Ica Fencing

The objective was to determine the reduction of sound pressure through acoustic barriers, knowing the factors that affect the propagation of its acoustic emission, the methodology was the quantitative design, explanatory level, pre-experimental type, pre and post-test, based on studies of behaviors of other barriers such as noise mitigating measures; Two sound level meters were used to measure noise, one of which served as a reference since the sound spectrum due to traffic has a varied behavior. The results obtained in the tests carried out in the field and office work, allowed us to corroborate the Equivalent Continuous Sound Pressure Level (LAeqT). We conclude that Calle Lima 1ra. block and 1st. block Av. Grau, exceeds the standard limits established in the S.D.N ° 085-2003-PCM Words.
