What are the auditory characteristics of brown noise?

Brown noise, also known as Brownian noise or red noise, is a type of sound signal characterized by a power density that decreases by 6 dB per octave with increasing frequency. This makes it deeper and richer than white or pink noise, resembling the sound of a strong waterfall or heavy rain. Understanding the auditory characteristics of brown noise can help you appreciate its applications in sound therapy and relaxation.
