Fresnel Diffraction Over Sound Barriers

  • John M. Eargle


Freeways are often isolated from nearby residential areas by barriers in order to cut down on noise from vehicles. The barrier height is determined from the desired amount of noise loss. In Figure 16A, S represents a line source, such as a busy freeway, and the barrier is actually a long wall viewed along its end. R represents a target residence where a certain amount of sound attenuation is desired, as compared to the case where there is no barrier.
