Quantitative measurement of 1-f noise and membrane theory

"1/f noise" in music: Music from 1/f nOiSe

The spectral density of fluctuations in the audio p wer of many musical selections and of English speech varies approximately s l/f (f is the frequency) down to a frequency of 5X 10 -4 Hz. This resultAmplies that he audio-power fluctuations are correlated over all times in the same manner as "l/f noise" in electronic components. The frequency fluctuations of music also have a 1/f spectral densi...

Pulses and 1/f Noise

Low-frequency fluctuations with a 1/f frequency spectrum were first noticed by Johnson [1] in thermionic-emission currents in vacuum tubes, and exist in a very wide range on phenomena. A feature common to most of these phenomena is that they involve a quasirandom sequence of pulses on the microscopic scale. The spectrum of energies associated with a short pulse of characteristic width Δt is rou...

Estimation and Interpretation of 1/f Noise 1 Running head: ESTIMATION AND INTERPRETATION OF 1/f NOISE Estimation and Interpretation of 1/f Noise in Human Cognition

Recent analyses of serial correlations in cognitive tasks have provided preliminary evidence for the presence of a particular form of long-range serial dependence known as 1/f noise. It has been argued that long-range dependence has been largely ignored by mainstream cognitive psychology even though it accounts for a substantial proportion of variability in behavior (e.g., Gilden, 1997, 2001). ...

On 1/f Noise

Due to the fact that 1/f noise gains the increasing interests in the field of biomedical signal processing and living systems, we present this introductive survey that may suffice to exhibit the elementary and the particularities of 1/f noise in comparison with conventional random functions. Three theorems are given for highlighting the particularities of 1/f noise. The first says that a random...
