Yes, the fence panels have a high acoustic barrier affect compared to wood fencing. Noise was one of the main reasons I installed six foot panels along a 75 foot run. So far it has cut down significantly the noise coming from an adjacent condominium complex to the south and the neighbors to the west. A taller panel would likely offer even more noise blockage.
