You can create an enormous zone of absolute silence. All sounds in this zone are instantly deafened.  For the duration, no sound can be created within or pass through a 60-foot-radius sphere centered on a point you choose within range. Any creature or object entirely inside the sphere is immune to thunder damage. Casting a spell that includes a verbal component is impossible there. You may choose to be affected by this spell or not. If not, sounds you produce, including footsteps, breathing, etc. are audible as normal.
