Novel system guides the blind by turning images into music

By - July 5, 2012 1 Picture
Sensory substitution devices work by converting one type of sensory input into another – examples would be systems such as CASBLiP and EYE 21, which allow the blind to “see” by assigning sounds to images. Now, a team of researchers at the Hebrew University of Jerusalem have created a similar wearable device, known as EyeMusic. It “employs pleasant musical scales to convey visual information,” and could one day help the visually impaired more easily perform tasks that the rest of us take for granted. Read More

Heeee-ya: Dragon Grip puts 1970s kung fu in the palm of your hand

By - May 11, 2012 4 Pictures
Imagine if you could accompany all those cool new moves you've just learned from Mortal Combat or reruns of Bruce Lee's finest celluloid moments with some genuine sound effects ... it would be like actually being in the game or movie. With a Dragon Grip in your Fist of Fury, that's precisely what's on offer. The joystick-like device is pre-loaded with fighting sounds inspired by the cheesy-but-classic kung fu movies of the 1970s like Enter the Dragon, that had all the kids in our neighborhood running around barefoot and shirtless with red lipstick wounds painted across their chests.

iZotope Iris - a new sampling re-synthesizer that lets you visually transform sound

By - May 8, 2012 8 Pictures
If you've ever dabbled in the creation of crazy sound effects for home movies, other-worldly audio to complement the battle sequences in a new alien gaming app or strange new loops for digital dance music, you quickly start to appreciate just what a complicated process sound design can be. What with noise generation, pulse and velocity modulation, parallel and series filters, and various other filters, oscillators and envelopes to contend with, the process can hardly be described as fun. A new sample-based synthesizer suite from iZotope seeks to change all that. Both a powerful tool for design pros and an enjoyable and easy way for newbies to dive in and experiment, Iris allows users to manipulate, tweak and layer sounds using the kind of visual editing tools you might find in graphic design packages and discover otherwise hidden sonic treasures.

“Noise sponge” cuts jet engine noise at the source of combustion

By - May 3, 2012 2 Pictures
Anyone living near an airport will tell you that combustion engines can be pretty noisy things. The combustion process in jet and other industrial engines can generate sound waves so powerful they can cause intense pulsations that can shake the engine and accelerate mechanical failure. Using a sponge-like material, researchers at the University of Alabama have managed to significantly quiet combustion at the source, providing the potential to make work environments safer, extend the life of valuable equipment, and maybe let those living near an airport sleep a little easier.

Vibrating stool puts drummers in touch with their bottom end

By - March 28, 2012 12 Pictures
The thunderous punch of a bass drum is the time-honored foundation on which all of rock 'n' roll is built. That thud that hits you in the chest and moves your whole body … it taps into a deep and primal place in our subconscious. But while the crowd is enjoying the power of the bass drum amplified through huge sub-woofers, the poor drummer himself is usually hearing a poxy, paper-thin, bassless pop from a tiny onstage foldback speaker. Trying desperately to feel the bass, they often turn the onstage monitors up to ear-splitting volumes, but you just can't get that kind of low end out of small speakers. Enter the BC2 (formerly known as the BumChum) from Britain's Porter and Davies - a simple two-part system that takes the bass drum signal and literally shakes the drummer's butt with it through a vibrating stool.

Japanese team invents device that silences the overly-wordy

By - March 2, 2012 1 Picture
For those who don't suffer the talkative gladly, a pair of Japanese researchers may have come up with just the thing - a portable device that can painlessly jam a person's speech from up to 30 meters (98 ft) away. Ingeniously dubbed the "SpeechJammer," you aim it like a gun and, if it's anywhere near as effective as the Delayed Auditory Feedback exhibit I tried at my local science museum, it works like a charm.

Alexander Graham Bell’s first sound recordings restored to life

By - February 21, 2012 3 Pictures
Recently, and for the first time in living memory, sound recordings made in 1881 at Alexander Graham Bell's Volta Laboratory Association have been heard aloud. The experimental phonographs made by the association where Bell worked alongside instrument-maker Charles Sumner Tainter and chemist Chichester A. Bell are thought to be the oldest preserved sound recordings intended for playback. Read More

SonicNotify: The inaudible QR codes your smartphone can hear

By - February 8, 2012 1 Picture
A new startup called SonicNotify has developed a technology that will enable smartphone apps to receive data via high frequency sound inaudible to the human ear. Though limited, the signals would be sufficient to transmit, say, a web address that could be automatically opened by your smartphone. These frequencies could be embedded into any audio being played through a speaker, and provide contextual information to the user. So, museums and art galleries could effectively transmit detailed information on their exhibits via their apparently silent PA systems. The cliche applies, I'm afraid: the possibilities are unending.

Researchers create invisibility cloak for sound

By - December 22, 2011 1 Picture
Many of the current experimental "invisibility cloaks" are based around the same idea - light coming from behind an object is curved around it and then continues on forward to a viewer. That person is in turn only able to see what's behind the object, and not the object itself. Scientists from Germany's Karlsruhe Institute of Technology have applied that same principle to sound waves, and created what could perhaps be described as a "silence cloak." Read More

Minimalistic Bluetooth speaker is activated by twisting the cap

By - November 25, 2011 8 Pictures
Bluetooth speakers are not particularly complex devices in terms of operation - you just pair them with a Bluetooth-enabled device, adjust the volume and enjoy the sound. However, a duo of industrial designers have created the Hidden Radio And Bluetooth Speaker in an attempt to make it even simpler and more intuitive. The unit is also claimed to offer an impressive 30 hours of battery life. Read More
