Geophysical Research Letters, 2023 Water discharges at hydroelectric dams on the Imjin River, which flows through North and South Korea, generate abrupt water level increases downstream. We assessed infrasound signals from water discharges using an infrasound array located ∼32 km from the

Annoyance of Audible Infrasound [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 1987 Contours of equal annoyance were determined for pure tones in the frequency range 4 – 31.5 Hz. The curves show a narrowing of the dynamic range of the ear at low frequencies. The same pattern is seen for equal loudness curves, and the results support the theory that the annoyance of infrasound is closely related to the loudness sensation.

Remotely imaging seismic ground shaking via large-N infrasound beamforming
Communications Earth & Environment, 2023 Seismic ground motion creates low-frequency atmospheric sound (infrasound) that is detectable at remote sensor arrays. However, earthquake infrasound signal analysis is complicated by interference between multiple waves arriving at sensors simultaneously,

Inhibitory effects of low decibel infrasound on the cardiac fibroblasts and the involved mechanism
Noise and Health, 2017 Introduction: Infrasound is a mechanical vibration wave with frequency between 0.0001 and 20 Hz. It has been established that infrasound of 120 dB or stronger is dangerous to humans.

Acoustic Rocket Signatures Collected by Smartphones
SignalsRockets generate complex acoustic signatures that can be detected over a thousand kilometers from their source. While many far-field acoustic rocket signatures have been collected and released to the public, very few signatures collected at distances ...

The Journal of the Acoustical Society of AmericaWaterfalls are long-lasting sources of continuous infrasound with relevance to multiple acoustic fields. This paper presents infrasonic observations of 11 waterfalls spanning wide ranges of hydraulic power, discharge, and height. The waterfall recordings had similar spectral shapes, including an abrupt rise from low-frequency background noise, a mid ...

Mechanical Filter-Based Differential Pressure Fiber-Optic Fabry-Perot Infrasound Sensor
IEEE Photonics Journal, 2021 A differential pressure fiber optic infrasound sensor based on a mechanical filter was developed, for the detection of infrasound within the frequency range of 0.01--1 Hz.
