The phenomenon is known as diffraction.
Diffraction is phenomena that occurs when a wave encounters an obstacle. This happens when a wave reaches an obstacle that is comparable in size to it.
Reflection, Refraction, and DiffractionLike any wave, a sound wave doesn't just stop when it reaches the end of the medium or when it encounters an obstacle in its path. Rather, a sound wave will undergo certain behaviors when it encounters the end of the medium or an obstacle. Possible behaviors include reflection off the obstacle, diffraction around the obstacle, and transmission (accompanied by refraction) into the obstacle or new medium. In this part of Lesson 3, we will investigate behaviors that have already been discussed in a previous unitand apply them towards the reflection, diffraction, and refraction of sound waves.
Large obstacles reflects sound waves. If you shout in front of a valley the sound wave travels in all directions and is reflected by an obstacle such as a wall or a cliff.
Sound originates right from the one where vibration of material occurs.

Diffraction is phenomena that occurs when a wave encounters an obstacle. This happens when a wave reaches an obstacle that is comparable in size to it.
In general waves can: Wrap around the obstacle. This happens when the wavelength is larger than obstacle size. Bounce back as an echo off the obstacle. This happens when the wavelength is shorter than the obstacle size. Be absorbed by the obstacle. This occurs when the natural frequency of the obstacle matches the frequency of the wave...so-called resonance. Pass through the obstacle. There are several ways this can happen. But visible light passing through a glass window is one example.

diffract
well sound i out "occurs" but you spell it occurs

Sound
the sound´s frequency decreases
