Should limit values be set for infrasound caused by wind turbines? [PDF]
International Journal of Occupational Medicine and Environmental HealthThe study focuses on setting outdoor exposure limits for wind turbine infrasound, as most countries currently have no specific limits for this type of noise.

Infrasound exposure is linked to aversive responding, negative appraisal, and elevated salivary cortisol in humans [PDF]
Frontiers in Behavioral NeuroscienceIntroductionInfrasound describes sound wave frequencies below 20 Hz, which are typically imperceptible to humans. Some animals perceive and demonstrate aversion to infrasound, raising concerns about its potential adverse effects as an anthropogenic ...

Uncertainty Quantification for Infrasound Propagation in the Atmospheric Environment
Applied Sciences, 2022 The propagation of infrasound in the atmosphere is influenced by atmospheric environmental parameters, which affect the precise localization of the infrasound source. Therefore, it has become crucial to quantify the influence of atmospheric environmental

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

Temporal integration of infrasound at threshold. [PDF]
PLoS One, 2023 Infrasounds are signals with frequencies below the classical audio-frequency range, i.e., below 20 Hz. Several previous studies have shown that infrasound is audible as well, provided that the sound level is high enough. Hence, the sound pressure levels at threshold are much higher than those in the classical audio-frequency range.

Progress in Biophysics and Molecular Biology, 2007 Definitions of infrasound and low-frequency noise are discussed and the fuzzy boundary between them described. Infrasound, in its popular definition as sound below a frequency of 20 Hz, is clearly audible, the hearing threshold having been measured down to 1.5 Hz. The popular concept that sound below 20 Hz is inaudible is not correct.
