Zebrafish aversion to infrasound in an open field test. [PDF]

Front Behav Neurosci, 2022
Aquatic species are capable of detecting infrasound (sub-20 Hz frequencies) which may be a source of anthropogenic pollution and have a detrimental impact on the environmental fitness of fish. Infrasound is generated by infrastructure, producing acoustic

Should limit values be set for infrasound caused by wind turbines? [PDF]

Int J Occup Med Environ Health
The study focuses on setting outdoor exposure limits for wind turbine infrasound, as most countries currently have no specific limits for this type of noise.

Quantized Information in Spectral Cyberspace. [PDF]

Entropy (Basel), 2023
The constant-Q Gabor atom is developed for spectral power, information, and uncertainty quantification from time–frequency representations. Stable multiresolution spectral entropy algorithms are constructed with continuous wavelet and Stockwell ...

Infrasound generation by tornadic supercell storms [PDF]

, 2008
Acoustic wave generation by turbulence in the stratified, moist atmosphere is studied. It is shown that in the saturated moist air turbulence in addition to the Lighthill's quadrupole and the dipole sources of sound related to stratification and temperature fluctuations, there exist monopole sources related to heat and mass production during the ...

Inhibition of astroglial hemichannels ameliorates infrasonic noise induced short-term learning and memory impairment. [PDF]

Behav Brain Funct, 2023
As a kind of environmental noise, infrasonic noise has negative effects on various human organs. To date, research has shown that infrasound impairs cognitive function, especially the ability for learning and memory.

Infrasound and the Avian Navigational Map [PDF]

Journal of Navigation, 2001
Birds can accurately navigate over hundreds to thousands of kilometres, and use celestial and magnetic compass senses to orient their flight. How birds determine their location in order to select the correct homeward bearing (map sense) remains controversial, and has been attributed to their olfactory or magnetic senses.

Automated Chirp Detection with Diffusion Entropy: Application to Infrasound from Sprites [PDF]

arXiv, 2005
We study the performance of three different methods to automatically detect a chirp in background noise. (1) The standard deviation detector uses the computation of the signal to noise ratio. (2) The spectral covariance detector is based on the recognition of the chirp in the spectrogram.

Autocorrelation Infrasound Interferometry

Journal of Geophysical Research: Solid Earth, 2021
AbstractSeismic and infrasound multistation ambient‐noise interferometry has been widely used to infer ground and atmospheric properties, and single‐station and autocorrelation seismic interferometry has also shown potential for characterizing Earth structure at multiple scales.

Infrasound generation by turbulent convection [PDF]

arXiv, 2004
Low frequency acoustic wave generation is studied taking into account the effect of stratification, inhomogeneity of background velocity profile and temperature fluctuations. It is shown that for the typical parameters of convective storms the dipole radiation related to temperature inhomogeneities is at least of the same order as radiation of ...
