help visualize sound propagation and energy transfer. The film also discusses sound directionality and interference patterns created by multiple sound sources. Keywords sound waves, loudspeaker ...

Interference can arise with one source of waves where the waves travel different distances before meeting. The difference in the distance travelled (the path difference) must be a full number of ...

Diffraction of a low frequency sound wave around a barrier. Note that the barrier does not create a sound shadow in the area of the lower right-hand corner. Barriers not built for acoustical purposes ...
