Tracking noise in noise.

The Journal of the Acoustical Society of America, 2011
Very often one wants to track one type of noise embedded in another noise. In addition, the noises may be nonstationary. For example, suppose one wants to track in time and or space a reverberation type noise that is embedded in an background ambient noise.

Low-noise noise

The Journal of the Acoustical Society of America, 1985
A practical method of computation is described for making periodic signals V(t) which have a given frequency spectrum and which minimize the variance 〈(V2−〈V〉2)2〉 in power as a function of time. These signals can be used to measure the spectral response of a system (the transfer function): They represent a significant improvement over traditional ...

Noise correlation

Magnetic Resonance in Medicine, 1991
AbstractCalculations and experiments that provide support for our previously stated theorem are presented: If two coils simultaneously receiving magnetic resonance signals from the same anatomic region exhibit zero mutual inductance, there can be no correlation of the noise.

Noise modeling, noise experiment, and noise inversion

The Journal of the Acoustical Society of America, 2005
Recent developments in inverting ambient noise to obtain bottom reflection properties originated from an understanding of noise behavior and from noise modeling. Sea-surface noise can be modeled equivalently as a ray, wave, or mode phenomenon, but often the ray or flux approach provides the most insight (explaining, e.g., the noise-notch or low ...

Chasing noise [PDF]

open access: possibleJournal of Financial Economics, 2012
We present a simple model in which rational but uninformed traders occasionally chase noise as if it were information, thereby amplifying sentiment shocks and moving prices away from fundamental values. In the model, noise traders can have an impact on market equilibrium disproportionate to their size in the market.

Noise And Noise Nuisance

2002
Abstract There is no adequate legal definition of noise and its measurement and control are often complicated. Noise is also perceived differently by different individuals and in some respects is a social construct. Changes in lifestyle affect the ways in which problems are perceived and defined.

The Noise in Noise

2023
This book aims to thoroughly examine noise’s conceptual potencies and explore and amplify its epistemic consequences. The author explores the prospect of different “contextures” of a present made volatile by noise. In a moment when our species exhibits the capacity of global-scale coordination and the design of robust, adaptable social systems, we need

Noise Audiometer

Journal of Speech and Hearing Research, 1972
The displacement of a threshold from its measured-in-the-quiet value to the value it takes in the presence of another sound is masking. Measurement of that displacement is masking audiometry. Measurement of displacements at a large number of frequencies produces a masking pattern.

Intervalley Noise

Journal of Applied Physics, 1960
A theory is developed for the spectrum of electrical noise due to electron transitions between several quasi-isolated groups of states, in the general case where each group may carry part of an electric current. It is applied to the noise due to transitions between valleys of the conduction band of germanium, and the possibility of observing this noise
