GUI with Anchor editor open
Kind of explaining the basics

1.15+ GUI with the recent sounds on display

The "circle" made of glowstone represents the range of an Anchor set to 16 blocks.

You can set up to 10 anchors per world.
Each anchor muffles the selected sounds in a configurable radius (max 32 blocks).

Too lazy to open your inventory and click the button? well, use a key! 
(empty by default, we don't want those nasty "overlap", right?)
