Fluctuations in many systems such as traffic, avalanches, the stock market, or electronic devices often have a power spectral density that is often approximately inversely proportional to the frequency. This means that the low frequency components of the noise have a higher amplitude than the high frequency components of the noise. There is no universally accepted explanation for this. I will describe a few systems that exhibit 1/f noise and a few models that are used to describe the noise.
