Wave of thunder

A blast of thunderous energy erupts from you in a 15-foot cube. Each creature within that area must make a Constitution saving throw. On a failed save, the creature takes 2d8 thunder damage and is hurled 10 feet away from you. On a successful save, it takes half damage and remains in place.

Any unsecured objects fully within the cube are also pushed 10 feet away from you. The spell creates a booming thunderclap that can be heard up to 300 feet away.

At Higher Levels. When cast using a spell slot of 2nd level or higher, the spell deals an additional 1d8 damage for each slot level above 1st.
