Silencing nuisance noise with an acoustic cloak
Noise pollution is a key issue facing policy makers in urban areas. In a recent development that might help town planners, researchers have proposed a design for a new sound-proofing device, an acoustic 'cloak', that could be 100 per cent effective. This suggests that, one day, buildings could be adapted to fully protect their inhabitants from external noise. An acoustic cloak is capable of ...

EPUK calls for quieter classrooms for better exam results
Communities all over the country are preparing to promote practical solutions to noise problems during Noise Action Week 2011 (May 23rd – 27th). A major focus this year is schools and the problems noise can cause in and around the learning environment. Too much noise can significantly impact on both student and teacher performance. A recent study by London South Bank University found that ...

Composing urban soundscapes
Currently architecture is dominated by the visual sense. The dominance of visual culture seems to have ‘deafened’ our aural experiences. We cannot avert our ears in the way we can our eyes from unwanted stimulus, the constant bombardment by our culture may have already caused us to have surrendered to noise (unwanted sound). White wires spilling from our ears indicate a rejection of urban ...

ASTM E2478 - 11 Standard Practice for Determining Damage-Based Design Stress for Glass Fiber Reinforced Plastic (GFRP) Materials Using Acoustic Emission
The damage-based design approach will permit an additional method of design for GFRP materials. This is a very useful technique to determine the performance of different types of resins and composition of GFRP materials in order to develop a damage tolerant and reliable design. This AE-based method is not unique, other damage-sensitive evaluation methods can also be ...

Berkeley researchers create first hyperlens for sound waves
Ultrasound and underwater sonar devices could “see” a big improvement thanks to development of the world’s first acoustic hyperlens. Created by researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), the acoustic hyperlens provides an eightfold boost in the magnification power of sound-based imaging technologies. Clever physical manipulation of the ...

Dark energy from the ground up: Make way for BigBOSS
Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, “supernovae” for short, certainly works: it’s how dark energy was discovered in the first place. Other independent techniques, such as weak gravitational lensing and baryon acoustic oscillation, also promise great power but are as yet unproven. These three techniques all have a share of ...
