Infrasounds, #3

The roar of a tiger contains audible sounds and infrasounds of 18 Hz and lower—which can penetrate solid objects like walls and even pass through mountains. Its prey feels the infrasounds in addition to the threatening roar—usually the last thing the victim hears—which can reach 114 decibels a few feet away (25 times as loud as a gas lawn mower). Humans can feel the tiger’s roar, a sensation that can cause momentary paralysis, even in trainers who have worked with tigers for years. Infrasounds have been linked to spooky events, as well. Mysteriously snuffed out candles, weird sensations and shivers down the spine may be due to infrasound and may produce a range of bizarre effects in humans including anxiety, sorrow, chills, feeling uneasy, feelings of revulsion or fear, or making people feel vaguely odd or that events are occurring. It’s the holiday season. Find yourself an organ concert and listen to the music of the season. Revel in the infrasounds from the very low pedal pipes on a huge pipe organ! Pay attention to what you "feel" versus what you "hear."
