A 5.75m high noise barrier is used to attenuate sound from a roadway adjacent to a residential subdivision. The height of the noise source is 1.25m and the height of the receiver is 2.25m. The distance from the noise source to the noise barrier is 22.00m. The distance from the noise barrier to the center of the rear yard of the residences is 11.00m. Determine the Path Length Difference in meters (accurate to 4 dec.pl.) that is created by the noise barrier.
