Thunderous Wave

You clap your hands or produce a loud noise in some manner, creating a burst of powerful sound that ripples outward from you. Each creature other than yourself within 30 feet of you must succeed on a Constitution saving throw or take 10d6 thunder damage, is deafened for 1 minute, is pushed 10 feet away from you, and is knocked prone. A creature that succeeds on its saving throw takes half as much damage, is pushed half as far away from you, and isn’t deafened or knocked prone.

At higher levels. When you cast this spell using a spell slot of 6th level or higher, it deals 1d10 extra damage and pushes targets an additional 10 feet away from you for each spell level after 5th.
