We find that whites bear less … noise than either blacks or Hispanics and that blacks tend to experience more traffic noise than Hispanics. While every … Metropolitan Statistical Area (MSA) showed that blacks experienced relatively more noise than average, such a result did not hold …

A sub threshold signal is transmitted through a channel and may be detected when some noise with known structure and … proportional to some level - is added to the data. There is an optimal noise level, called of stochastic resonance, that … corresponds to the minimum variance of the estimators in the problem of recovering unobservable signals. For several noise …
