Echolocation

You emit a constant noise, either through an instrument, or your own voice and magically project it over a distance of 500 feet. For the duration of the spell, you can detect the direction, distance, and size of any creature within the spell's range.

Any creature detected by this spell is able to hear the noise as a faint hum and can make a perception check with a DC equal to your spellcasting ability modifier to determine your direction.

At Higher Levels: For every spell level above 2nd, the range of this spell increases by 100 feet.
