1. An acoustic tile, comprising:
a structure with at least a first layer and a second layer; and
a first plurality of openings formed in the first layer of the structure;
a second plurality of openings formed in the second layer of the structure, wherein the first plurality of openings is greater in number than the second plurality of openings;
the first and second plurality of openings configured to direct sound waves hitting the structure in multiple different directions through the first layer and the second layer to absorb a majority of the sound waves and inhibit the sound waves hitting the structure from reflecting off of the structure to dampen sound.
