THE WAR ON NOISE: Noise is an unwanted signal -- The noise-signal duality: one person's signal is another person's noise -- Information theory made a science out of the war on noise -- Channel noise randomly flips bits -- Noise limits channel capacity -- Noise can sometimes help -- NOISE IS A NUISANCE: Noise is a private nuisance if it substantially and unreasonably interferes with someone's use and enjoyment of land -- Noise is a public nuisance if it substantially interferes with a right common to the public -- E-mail spam counts as a cyber-noise nuisance -- THE NUISANCE THAT DEFERS: Noise-induced hearing loss is a common health hazard -- Noise can damage the inner ear's frequency detectors -- Noise increases stress -- Noise can harm simpler animals -- WHITE NOISE AIN'T SO WHITE: White noise is independent in time and has a flat spectrum, and so is physically impossible -- There are infinitely many types of white noise -- Most noise is impulsive -- Chaos and fuzz can produce white noise -- Real noise is colored noise because its frequency spectrum is not flat -- Thermal noise fills the universe -- Even black holes emit noise, and die -- FIGHTING NOISE WITH NOISE: The ideal low-pass filter resembles wideband noise in digital sampling -- Noise helps shape the spectrum of signals -- Noise cancellers learn noise patterns to annihilate them -- Delilah's secret: wireless signals can hide in noise -- THE ZEN OF NOISE: STOCHASTIC RESONANCE: many physical and biological systems display a stochastic resonance noise benefit because they are nonlinear systems -- The "forbidden interval" theorem: model neurons benefit from noise if the average noise lies outside the "forbidden interval" -- Noise can benefit nanosystems and the molecular motors of life.

Enhanced descriptions from Syndetics:

From the well-known science commentator and bestselling author of Fuzzy Thinkingcomes a revelatory look at the phenomenon of noise A celebrated maverick in the world of science, Bart Kosko introduced'and continues to popularize in print and television media'the revolutionary concept of fuzzy logic. In his latest book, he provides the first scientific history of noise aimed at the general reader. Noise is a social nuisance, a cause of deafness and high blood pressure, and an all-around annoyance. But what is noise really? As Kosko simply states, ?Noise is a signal that you don't like.' It occurs at every level of the physical universe, from the big bang to blaring car alarms. Today, noise is considered the curse of the information age, but, in fact, not all noise is bad. Debunking this and many other commonly held beliefs about noise, Kosko gives readers a vivid sense of how deeply noise permeates both the world around us and within us. Along the way he covers many compelling topics, from noise's possible role in the ice ages to noise pollution laws, the use of noise to generate synthetic speech, and Hedy Lamarr's contribution to noisy wireless communication. The result is a vastly entertaining and illuminating scientific journey that promises to do for noise what James Gleick did for chaos'make it vital, fascinating, and relevant.

Includes bibliographical references (p. [167]-231) and index.
