Is red noise different from brown noise?

The difference between Red and Brown noise has to do with their frequency, intensity and how they are produced.

Brown Noise is generated with one tone. It’s basically a combination of all the sounds we hear in our daily lives.

Brown noise is a smooth sound with a slow, wavering pitch. Red noise is a combination of multiple frequencies which are very close together.

Red noise is a faster, harsher sound with a deeper pitch. This is the noise a dog hears before a storm, or a human hears before an airplane takes off.
