This is the Średnia głośność icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
The main part of the logo is made of two connected shapes. On the left is a triangle with slightly rounded corners, and connected to it is a triangle facing left but cut in half so that the two shapes together look like a speaker facing to the right. Two semi circular lines are coming out of the speaker and represent sound waves.
