Why Music Makes You Happy
My Image
People love music for much the same reason they're drawn to sex, drugs, gambling and delicious food, according to new research. When you listen to tunes that move you, the study found, your brain releases dopamine, a chemical involved in both motivation and addiction.
Even just anticipating the sounds of a composition like Vivaldi's "Four Seasons" or Phish's "You Enjoy Myself" can get the feel-good chemical flowing, found the study, which was the first to make a concrete link between dopamine release and musical pleasure.
The findings offer a biological explanation for why music has been such a major part of major emotional events in cultures around the world since the beginning of human history. Through music, the study also offers new insights into how the human pleasure system works.Image Source
"You're following these tunes and anticipating what's going to come next and whether it's going to confirm or surprise you, and all of these little cognitive nuances are what's giving you this amazing pleasure," said Valorie Salimpoor, a neuroscientist at McGill University in Montreal. "The reinforcement or reward happens almost entirely because of dopamine."
"This basically explains why music has been around for so long," she added. "The intense pleasure we get from it is actually biologically reinforcing in the brain, and now here's proof for it."
In a previous study, Salimpoor and colleagues linked music-induced pleasure with a surge in intense emotional arousal, including changes in heart rate, pulse, breathing rate and other measurements. Along with these physical changes, people often report feelings of shivers or chills. When that happens during a listening experience, Salimpoor's group and others have found evidence that blood flows to regions in the brain involved in dopamine release.
To solidify the dopamine link, the researchers recruited eight music-lovers, who brought to the lab samples of music that gave them chills of pleasure. Most picks were classical, with some jazz, rock and popular music mixed in, including Led Zeppelin and Dave Matthews Band. The most popular selection was Barb[e]r's Adagio for Strings.
After 15 minutes of listening, scientists injected participants with a radioactive substance that binds to dopamine receptors. With a machine called a PET scanner, the scientists were then able to see if that substance simply circulated through listeners' blood, which would indicate that they had already released a lot of dopamine, and that the dopamine was tying up all available receptors.

Damn commercials - I thought most modern TVs had a smart sound feature that controlled this very thing?

Acoustic Levitation
Acoustic levitation is a method for suspending matter by using radiation pressure from intense sound waves - ex. an ultrasound emitter and reflector generate a sound pressure field. Some methods can levitate objects without creating sound heard by the human ear, others produce some audible sound. Apparently ants, spiders and ladybugs have endured this trick.

Here's an annoying video about it (turn down your volume a bit):
This is an acoustic levitation chamber I designed and built in 1987 as a micro-gravity experiment for NASA related subject matter. The 12 inch cubed plexiglass Helmholtz Resonant Cavity has 3 speakers attached to the cube by aluminum acoustic waveguides.
By applying a continuous resonant(600Hertz) sound wave, and by adjusting the amplitude and phase relationship amongst the 3 speakers; I was able to control levitation and movement in all 3 (x,y,z) axis of the ambient space.
This research was used to show the effects of micro-gravity conditions that exist in the space shuttle environment in orbit, but done here on Earth in a lab.
This is not "anti-gravity." So don't waste time arguing something pointless.
