What Is Green Noise?

Green noise is a type of sound that falls within the mid-frequency range of the sound spectrum, typically around 500 Hz. It is often associated with natural environments, as it closely resembles sounds found in nature, such as the gentle ebb and flow of ocean waves, the steady pitter-patter of rainfall, or the soft rustling of tree leaves in the wind. Although there is limited research on the benefits of green noise, some studies suggest it can help mask environmental noises that may disrupt sleep.
