Thunderous echo (WIP)

You puff up your chest, and the muscles around your lungs and in your throat tighten and brace, as you let out an ear piercing scream which can be heard from up to 200 ft, the sound of this violent screech can echo for drastic destructive power. This screech deals 2d6 thunder damage in a 30 ft range and 15 ft cone and can be cast again as a bonus action for 1d6 thunder damage without using a spell slot if it has already been cast as an action during the same turn. Both attacks cause the target creature(s) to make a constitution saving throw, taking half damage on a successful save, and afflicting the deafened status effect on the creature(s) until the end of its next turn on a failed save. (The damage for both attacks of this spell increases by 1d6 every level above first.)
