Wall of Silence

Any creature within the sphere can’t be heard by creatures outside of the sphere and vice versa. Even if a spell magically amplifies the volume of the noise being made, no sound can leave or enter the sphere. Any creature or object entirely inside the sphere is immune to thunder damage, and spells that use or cause sound to happen, such as the Shatter spell or Vicious Mockery, automatically fails if trying to pass through or emulate from the other side of the sphere.
