By - December 30, 2012 7 Pictures
The idea of catching a sound in a bottle in order to listen to it later is one that many of us have toyed with, especially as kids. Unfortunately it isn't possible in the real world, at least not with a real bottle and nothing but a real bottle. However, Re: Sound Bottle is more than what it first appears to be, and its internal components means this particular bottle is capable of recording, remixing, and playing back sounds captured from all manner of different sources.

Sounds good: Argonne researcher represents data with music

Peter Larsen, of the Argonne National Laboratory in the U.S., decided to do something a little different: he represented microbial data with sounds. More specifically, he sonified data relating to bacteria collected from the western part of the English Channel. Read More

Software identifies bat species based on their calls

By - August 8, 2012 1 Picture
Everyone knows that it’s possible to identify different species of birds by their vocalizations, but did you know that it’s also possible to differentiate between different types of bats based on their echolocation calls? Well, now you do. So far, however, there hasn’t been a standardized system of doing so – it’s been left up to individual human listeners to decide on the closest match. That may soon no longer be the case, though, as the new online iBatsID tool comes into use. Read More

Scientists prove it's the same old song – only louder

If you suspect that songs today tend to sound the same, it turns out you're right. A group of Spanish scientists looked at a huge database of songs and analyzed their trends, publishing their results in the scientific journal Nature.

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
