Due to sound wave being absorbed and reflected .
Explanation:

- While other part of it gets reflected from the surface of the obstacle.
- As a result of which the intensity of sound wave decreases
- Now your ears receive this sound of diminished intensity and so they produce weak vibrations in the eardrums.
