Low Frequency Brown Noise with a frequency shift or sweeping over a 30 second period for a relaxing background listening and masking. There is a meditative quality created with the sweeping of the noise. Brown Noise is also called Red Noise and is noise based on low frequencies with little midrange or high frequencies. It sounds kind of like heavy ocean, thunder or a distant waterfall.
