Our good friends over at Sound + Vision just posted a great little explainer on crossovers, "the part of a loudspeaker that people least understand." (They're kind of like filters that send different parts of the input audio to different parts of the speaker.) It's a great way to actually figure out what's going on inside your boom-cubes (the preferred audiophile term for speakers, we assume). Read more over at S+V.
Predators of the threatened Mojave ground squirrel include badgers, coyotes, snakes, falcons, hawks, and U.S. military aerial strikes. That's because the squirrel makes its home in a section of California's Mojave Desert also used by the Air Force as a practice area. But the military has to make sure not to accidentally bomb the squirrels, them being threatened and all, and expends a lot of time and money trying to find them so as to avoid that.
Our sister publication, Sound + Vision, has an in-depth look at an earbud even more peculiar than the silicone-filled Sonomax Eers. This balloon-like creation notes the natural muscle-tensing reflex of the ear and is designed not to trigger it, meaning you need less volume for the same effect--ultimately much safer on the hearing-holes.
Cramming surround sound into an LCD TV is tricky. TV makers have tried but, to protect the screen, have ended up with bulky, subwoofer-less sets. Bass causes shaking that can blur images and damage pixels over time, and more speakers generally means broader frames. Now Bose has designed a 16-speaker setup for its HDTV that disperses audio from what looks like no more than a 46- inch LCD. Here’s how a subwoofer and room-filling virtual surround sound disappear into a case only a couple of inches thicker than other LCD TVs.
She manipulates simple laws of physics to create “bullets” made of sound waves

Chiara Daraio loves the pick and roll. As a former member of Italy's junior national basketball team, she knows that although the effect of the play is complex and devastating, its parts are simple. It goes like this: Daraio blocks a defender’s path, her teammate darts past, Daraio rotates away from the pursuing defender and waits, unguarded, for her teammate's quick pass and an open shot. Pick. Roll. Pass. Shoot. It's a straightforward process with a sophisticated result.
Yesterday we explained how to block the 233-Hz drone of the vuvuzela with software at home. Today, Host Broadcast Services, providers of the TV feed of the World Cup, announced that it has increased the EQ filtering on the back end, after viewer complaints about the controversial horn.
Long after the game has ended and the TV has been shut off, the vuvuzela continues to echo in our ears. The plastic stadium horn, blown by World Cup fans to celebrate such moments in a game as -- well, every moment -- has achieved unprecedented fame and rancor this Cup, as its B-flat drone is broadcast around the world.
From German blog Surfpoeten comes a DIY solution for home Cup-watchers driven to distraction by the stadium horns: a software filter that selectively mutes the particular frequency of the vuvuzela.
Want to know what a jam session between Jack White and Stevie Ray Vaughan might have sounded like, or how Billie Holliday would interpret the latest dreck from Avril Lavigne? Advances in artificial intelligence are resurrecting musical legends of the past, tapping into old recordings to establish a musician's style and personality, then applying those attributes to newer recordings of old songs, or even to songs the musician never played before.
Bark beetles plague the forests of Canada so furiously you'd think rivers of blood and the death of the firstborn would follow hot on their heels. So far, no one has stopped the beetle rampage that has destroyed 33 million acres of trees in British Columbia. However, scientists at Northern Arizona University (NAU) may have devised a way to turn back the beetle tide using sound recordings.
A desert people have developed a new weapon that uses sound instead of bullets. But this time, it will be used to control crowds instead of fighting giant worms or devious members of House Harkonnen. The Israeli Defense Ministry has contracted for the production of sonic-boom stun-guns called "Thunder Generator cannons," which they hope to use in crowd-control situations.
