An acoustic medium comprising:
- a fibrous acoustic material comprising a first portion and a second portion, wherein the first portion is electrically oriented and entangled within the second portion, wherein the first portion of the fibrous acoustic material comprises between about 10% and about 40% of the fibrous acoustic material.
A method of fabricating an acoustic medium, comprising:
- disposing a fibrous acoustic material to form a first layer;
- electrically orienting a first portion of the fibrous acoustic material to entangle the first portion of the fibrous acoustic material with a second portion of the fibrous acoustic material;
- and
- wherein the first portion of the fibrous acoustic material comprises between about 10% and about 40% of the fibrous acoustic material.
