Remote sensing with ambient noise
SEG Technical Program Expanded Abstracts 2009, 2009Ambient noise is ubiquitous in the ocean. For many years, this noise has been considered the unwanted part of the acoustic signal. However, recent studies have shown that the noise itself contains valuable information about properties of the ocean, Earth, and atmosphere. For example, distant storms have been observed using measurements of low-frequency

Intrusive Noise and the Ambient Noise Environment
The Journal of the Acoustical Society of America, 1970The extent to which an intruding noise source penetrates the general ambient noise environment in a community, serves as a useful indicator of the likely reaction of the community to that noise source. Available techniques using this approach generally provide a measure of community response based upon the absolute difference in level between the ...

Signal processing algorithms optimized for Gaussian noise may degrade significantly in a non-Gaussian noise environment. Therefore it is important to characterize the noise accurately before including its structure in the formulation of algorithms. A generic distribution suitable for modeling non-Gaussian ambient noise in the kurtosis range 1.8 >

Boothless audiometry: Ambient noise considerations
The Journal of the Acoustical Society of America, 2023Ambient noise in the test environment will impact signal detection during hearing threshold measurements due to psychoacoustic masking effects. Technical standards specify the maximum permissible ambient noise levels (MPANLs) for use during audiometric testing.

Passive Imaging with Ambient Noise
2016Waves generated by opportunistic or ambient noise sources and recorded by passive sensor arrays can be used to image the medium through which they travel. Spectacular results have been obtained in seismic interferometry, which open up new perspectives in acoustics, electromagnetics, and optics.

A model of ambient sea noise is developed under the assumption of a surface distribution of noise sources. Volume absorption and the effects of refraction and reflection over long-range paths are included. The derived directional noise field is expressed as a function of vertical arrival angle, with the parameters being velocity profile, surface ...

Whether noise is a nuisance or a signal depends on how it’s processed. By cross-correlating noise recorded at two sensors, researchers can retrieve the waves that propagate between them and extract details about the intervening medium.
