The article reports that exposure to extremely low frequency sounds, which are inaudible to most people, can raise cortisol levels and influence mood, suggesting a biological basis for unsettling or creepy feelings. It also describes a laboratory study where infrasound at eighteen Hertz increased stress hormones even when participants could not consciously hear it, and how this may contribute to haunted or eerie experiences.

This topic is of interest to psychology readers because it links environmental factors and physiological stress responses to perceived emotional states, highlighting how unseen stimuli can shape mood and interpretation of surroundings.

Infrasound Fire Suppression Goes Commercial

Sprinklers have long been the go-to fire protection for commercial properties and some residences. Dousing a fire in water not only puts out the flames but cools the surroundings and helps prevent reignition. But it requires complicated infrastructure and can damage buildings and their contents. Back in 2015, students were experimenting with an alternative fire extinguisher that used sound below the range of human hearing; now a company is pitching a version of that technology for replacing sprinklers.

As described by Ars Technica, this infrasound system can detect and put out a small kitchen fire in under a minute. But fire fighting experts warn that there’s a big difference between a fire small enough for a fire extinguisher to handle and the kinds of fires sprinklers put out. With lives at stake, the burden of proof is significant for Sonic Fire Tech and any other company that wants to get their infrasound “sprinkler” system cleared for use in buildings. (Image credit: I.

Some jərkoff put me on list "anti-AI". I thought this was accurate until I clicked it. Specifically said was: "Wrong about AI/Crypto, probably wrong about other things too." Since this's a way that numbskulls use to block others, I thought I might as well double-down. https://www.youtube.com/watch?v=_bP80DEAbuo

“With infrasound, you can seriously disorient people, and you can cause them to vomit, induce nausea, and, generally, incapacitate them.”

A small study found that individuals experienced negative affect and higher salivary cortisol when exposed to infrasound (18 Hz).
