You cannot be "parallel" to a sound wave! Sound waves travel in all directions from a center point, like a balloon that inflates. How can you be "parallel" to a balloon?
When a sound wave hits a "barrier", it is reflected (bounces back) and interferes with itself (with the incomming waves) and that interference would create peaks and dips (loud and silent areas).
If the barrier is elastic (such as a sheet of steel), if the frequency of the wave is the right one, it may create resonant vibrations within the barrier.

Along a parallel? Parallel to the surface would probably be diffusion.
