Amplify sound

You select a sound you can hear (example being your voice or a piano key), and amplify it. You mimic the sound exactly with your voice and shoot the sound in a 30 foot cone. Any creature in the cone takes 1d6 thunder damage, and anyone who can hear you outside the cone takes 1d4 thunder damage. This spell has no effect on anyone who can’t hear you, and is high enough pitch to shatter glass. Targets who cover their ears while in range of this spell have resistance to the thunder damage.

At higher Levels: The damage increases by 1d6 when you reach certain levels, and the range of your cone increases: 5th level (2d6 in cone, 2d4 outside) and an extra 10 feet, 11th level (3d6 in cone, 3d4 outside) and an extra 20 feet, and 17th level (4d6 in cone, 4d4 outside) and an extra 30 feet.
