If the wavelength of a wave is smaller than the dimensions of the obstacle it faces, it will get reflected by the obstacle. The second is due to the diffraction of sound over the wall. Waves of shorter wavelength spread out (diffract) less after passing through the slits, and the short wavelength leads to a smaller angle at which constructive interference (one wavelength path difference between the two waves) will occur. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. https://en.wikipedia.org/wiki/Kinetic_diameter. At my location that has a direct view of a freeway, noise can change from "not noticeable" to a surprising 65 db. As sound waves travel through a medium, they lose energy to the medium and are damped. Also, in AM the transmitted power goes waste in the transmitted carrier.
