Understanding Pink Noise: What Should It Sound Like?

Pink noise, also known as 1/f noise or flicker noise, is a random signal with equal energy emitted across all octaves. Its spectral density, characterized by a decrease in power in higher frequencies, creates a balance that is often described as more soothing and natural compared to white noise. Commonly found in nature, pink noise can be likened to gentle rain or steady ocean waves crashing onto a shoreline, offering various benefits such as masking disruptive noises, promoting relaxation, and improving sleep quality. For both personal and professional use, audio engineers, musicians, and everyday listeners can take advantage of pink noise to enhance their audio experiences.
