What happens to your body when you scream?
What happens to your body when you scream? The higher the scream’s roughness, the more it activates the brain’s amygdala, the more in danger a person feels. And, as the report’s able to quantify, a scream can scare the bejesus out of someone. Poeppel’s team points out that conversational speech has a relatively low volume, […]
What is the most efficient way to convert heat to electricity?
What is the most efficient way to convert heat to electricity? A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat flux (temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect (a form of thermoelectric effect). How do you calculate electrical efficiency? For an […]

What are sounds below 20 Hz called?
What are sounds below 20 Hz called? At the other end of the spectrum are very low-frequency sounds (below 20 Hz), known as infrasound. Elephants use infrasound for communication, making sounds too low for humans to hear. Because low frequency sounds travel farther than high frequency ones, infrasound is ideal for communicating over long distances. […]
