Hearing Icon in Material Style

This Hearing icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
This is a basic image of the human ear. It loosely shows some of the various curves, depressions, etc. one might have in their ear.

An icon of a Human Ear

In addition to the ear a "Not listen" icon would be great with an ear that is crossed with a single line.
