Active Hearing Process in Mosquitoes Nov 21, 2009
Insects have evolved diverse and delicate morphological structures in order to hear the naturally low energy of a transmitting sound wave. In mosquitoes, the hearing of acoustic energy, and its conversion into neuronal signals, is assisted by multiple individual sensory units called scolopidia. (Science Daily)
Detecting a silent bridge-killer Nov 8, 2009
An electrical transmitter is placed against concrete and emits a sound wave, which travels through the concrete and bounces back to a receiver. An engineer can analyze the resulting signal to determine the condition of the concrete. (Albany Times Union)
Hyperlens harnesses metamaterials for ultrasound, sonar Oct 28, 2009
7 times smaller than the wavelength of the sound wave used. The researchers said the acoustic hyperlens can be further improved to boost the magnification of sound-based imaging technologies such as ultrasound and sonar. (EETimes)
Light And Sound Vibrations Trapped Together In Nanocrystal For First Time Oct 27, 2009
"First, the interactions of the light and sound get stronger as the volume to which they are confined decreases. Second, the amount of mass that has to move to create the sound wave gets smaller as the volume decreases. We made the volume in which the light and sound live so small that the mass that vibrates to make the sound is about ten times less than a trillionth of a gram.". Eichenfield points out that, in addition to measuring high-frequency sound waves, the team demonstrated that it's... (Science Daily)

Simulated black holes may prove theory Sep 11, 2009
A group in Israel recently created a , accelerating atoms beyond the speed of sound to make it impossible for a sound wave to escape. Another group wants to use water waves to simulate black holes. (MSNBC -- Technology)
Acoustic tweezers can position tiny objects Aug 29, 2009
Because sound waves have pressure, they can push very small objects, so a cell or nanoparticle will move with the sound wave until it reaches the trough where there is no longer movement. The particle or cell will stop and "fall" into the trough. (EurekAlert!)
On intelligent robots Jul 30, 2009
On the subject of modelling, whilst it is true that you can't completely model neurons with integers, that is not the question - the question is can you model them with a sufficient accuracy - we don't model a sound wave precisely when we digitize it, but we are close enough that the digitisation process introduces less noise than all of the surrounding analogue processes. And of course all modern CPUs use 64bit integers as their preferred integer size, not 8bit. (Harper's Magazine)
Getting smarter Jul 20, 2009
Andrew Fisher, Shazam's chief executive, explained that the different sound waves make identification possible. "Every vocal performance has a different sound wave," he explained, "so it's being able to very quickly look at that pattern and compare it against the eight million songs we have on the database, make the match and bring the result back to the consumer in around about five to 10 seconds.".

Mystery Of Bat With Extraordinary Nose Solved Jul 8, 2009
The echoes of the sound wave convey a wealth of information on objects in the bat's environment. This bat from the remote rainforests of South East Asia received its name 58 years ago because of its mysterious trait. (Science Daily)
Humans can develop echolocation like dolphins and bats Jul 2, 2009
By using echolocation, "which is three-dimensional, and makes it possible to 'see' through materials that are opaque to visible radiation," it is possible to measure the distance of an object based on the time that elapses between the emission of a sound wave and an echo being received of this wave as it is reflected from the object. In order to learn how to emit, receive and interpret sounds, the scientists are developing a method that uses a series of protocols. (India Times, India -- Health/Science)
The pressure's off ... with ear tubes May 22, 2009
"But in kids sometimes, you just get thick fluid stuck behind the eardrum and it won't drain out. That causes a hearing loss because the sound wave just can't get through the eardrum to get to where he can hear it.". The procedure can be done earlier, however, if the infections are so bad that the kids must have antiiotics by shot or through an IV or if the kids have ruptured their eardrums.

New sensor to check medical equipment hygiene Apr 18, 2009
In this new process, a high frequency sound wave is passed through a disinfecting liquid to create bubbles that implode. The force of each implosion removes contaminate particles from surrounding materials. (India Times, India -- Health/Science)
EU woos young voters through MTV Apr 10, 2009
MTV is also inviting young people to take part in a "roaring sound wave" across Europe on 30 April, when they will all shout "Can you hear me Europe?". "Young people are the future of the European Union. We need their ideas and their active involvement. They need to know that their voice counts," said Commission Vice-President Margot Wallstrom.

Shifting Sound To Light: Better Computer Chips Mar 23, 2009
But by reversing that process, lead researchers Michael Armstrong, Evan Reed and Mike Howard, LLNL colleagues, and collaborators from Los Alamos National Laboratory and Nitronex Corp., used a very high frequency sound wave - about 100 million times higher frequency than what humans can hear - to generate light. This process allows us to very accurately see the highest frequency sound waves by translating them into light, Armstrong said ... However, the recent research takes those initial... (Science Daily)
