How seabirds navigate across thousands of miles of seemingly featureless ocean is one of nature's mysteries. It is known that seabirds use a range of cues including sight and smell to direct their ...

New research suggests that infrasound—low-frequency sound waves below human hearing—may explain creepy sensations often attributed to haunted places. Controlled experiments found that exposure to ...

Infrasound refers to acoustic waves with frequencies below 20 Hz that can propagate over thousands of kilometres in the atmosphere by interacting with layered wind and temperature fields. Energy ...

Infrasound is very low-frequency sound, below 20 Hertz (Hz), which humans typically can’t hear. It can come from natural sources like storms, or from anthropogenic sources like traffic. Some animals ...

Earthquakes sway buildings, buckle terrain, and rumble -- both audibly and in infrasound, frequencies below the threshold of human hearing. New computer modeling by a team of researchers indicates ...

The world is filled with sounds below the range of typical human hearing. These invisible noises, known as infrasound, can even come from within your home, stemming from old pipes, ventilation systems ...

University of Sydney provides funding as a member of The Conversation AU. At the centre of claims about wind farms allegedly causing health problems is the infrasound that wind turbines generate as ...

Infrasound refers to sound frequencies below the threshold of human hearing, around 20 Hz or less. There are a variety of natural sources of infrasonic emissions, including thunderstorms, avalanches, ...

It's no secret that wind farms appear to have fallen out of favour with the Coalition Government. The claim: Liberal Democrats Senator David Leyonhjelm says that it is "well established that ...
