Thunderous blast

You create three thunderous burst next to up to three creatures within range. Make a ranged spell attack for each burst. On a hit, you deal 1d12 thunder damage and the target is deafened until the end of your next turn. A deafened creature takes only half damage from this spell.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you create one additional burst for each slot level above 2nd.
