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.
