The Noise texture generates four different types of Procedural noise, and the settings give you the ability to produce a wide variety of noise effects. The four types of noise are:

Used for dull, non-reflecting materials or mesh emitters. channel of a Diffuse material. Figure 3 shows the settings that generate this noise pattern.
