abstract = "Barriers are among the most widely used strategy to control the ambient noise in the urban areas. However, the previous studies approve the inefficiency of the barriers to degrade low-frequency spectra noise. The technique of active noise control (ANC) employs to improve the performance
of passive noise barriers at the low-frequency noises. This study seeks to address the effect of employing an active noise control approach on the performance of an infinite barrier. For this purpose, the noise levels at the shadow zone and the neighboring building are measured for three cases,
without barrier, with barrier and with active noise barrier. Different locations for control sources and error sensors are investigated to improve the efficiency of the active noise barrier. The results confirm the positive impact of active noise control on the reduction of the noise level
in the shadow zone. Furthermore, the distribution of sound pressure levels in the shadow zone helps to define a suitable location for the transducers.",
