How to create such a noise texture

[Sylvana5E68]

Please help me create noise textures like here in the background, in Photoshop they are created very small, so I want to know how to create just such bold point textures with different shapes and in a random arrangement.

P.S - i need know how to create BACK background ( except hieroglyphs  )

You can create randomized Brushes based on a sampled brush. 

Though keep in mind that in Photoshop there is no such thing as an image hose (as of yet), so if you want to have different shapes that would necessitate creating different Brushes.

That might be a slightly blurred photo of countertop material.
