Spell effect

A wave of thunderous force sweeps out from you. Each creature in a 15-foot cube originating from you makes a Constitution saving throw. On a failed save, a creature takes 2d8 thunder damage and is pushed 10 feet away from you. On a successful save, it takes half as much damage and is not pushed.

Unsecured objects entirely inside the area are automatically pushed 10 feet away. The spell also creates a thunderous boom audible out to 300 feet.

At higher levels

When cast using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
