1/f Noise, also known as pink noise, is a type of signal or sound that has equal energy in all octaves. This means that its power decreases as the frequency increases, resulting in a balanced sound that is often perceived as more natural. It is commonly found in various systems, including electronic devices, biological processes, and even music. This noise is characterized by its fractal nature, where patterns repeat at different scales. It is often used in applications like audio engineering and environmental sound studies, as it can create a soothing background noise that masks other sounds, making it useful for relaxation and concentration.
