Wall of Sound

You create a wall of sound on a solid surface within range for the duration of the spell. The wall is an immobile, shimmering curtain of violently disturbed air. The wall is made up of 10 section, which are 10-foot squares each. These sections can be arranged as desired as long as the resulting wall all lies in one plane (flat) that stands vertically.

One side of the wall, selected during the casting of the spell, produces a voluminous roar that completely disrupts all communication, command words, verbal components, and any other form of organized sound within 30 feet. Additionally, creatures within 10 feet of the wall are deafened for 1d4 minutes if they fail a Constitution saving throw. On the other side of the wall, a loud roar can be heard, but communication is possible by shouting, and verbal components and command words function normally.

Anyone passing through the wall must make a successful Constitution saving throw or take 1d6 points of force damage and are deafened for 1d4+1 weeks.

A silence cast specifically for this purpose is able to dispel the wall; otherwise the wall destroys all silence spells that come into contact with it.
