This is a Audio Description icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,700 icons, all in the same style and quality.
This icon is depicting the letters AD with three curved lines emanating from it as if to indicate sound waves. The letters of the 'A' and 'D' are outlines and rest in the center of a curved rectangular shaped object.
