You attune your senses to the air in a sphere whose radius is 20 ft. The sphere is centered on you and moves with you. For the duration, you have advantage on all Perception checks that involve hearing, and every creature that moves at least 5 ft. within the spell's area must make a Dexterity saving throw against your spell save DC. On failure, you are aware of the creature's movements and the path that the creature takes within the area. Creatures that are gaseous, burrowed, or incorporeal, such as ghosts, are immune to this effect, and locations that do not contain air, including underwater locations, are excluded from the spell's area-of-effect.

At higher levels. When you cast this spell using a spell slot of 2nd level or higher, you can extend the radius of the effect by 10 ft. per spell level above 1st.
