Dissonant Vibration

You create vibrations in a 60-foot line in front of you. Creatures in that line must make a Constitution saving throw. On a failure, an affected creature takes 7d6 vibrational damage and is Deafened for the next minute, repeating the saving throw at the start of each of its turns to end this condition.

At Higher Levels. When you cast this spell by spending Mana points equal to a 6th-level spell or higher, the vibrational damage increases by 1d6 for each level above 5th. When cast as a 7th-level spell or higher, the damage becomes disruptive.
