KIT Researchers Succeed in Realizing a New Material Class
A research team lead by Professor Martin Wegener at the Karlsruhe Institute of Technology (KIT) has succeeded in realizing a new material class through the manufacturing of a stable crystalline metafluid, a pentamode metamaterial. Using new nanostructuring methods, these materials can now be realized for the first time with any conceivable mechanical properties. View More (2012-05-09)
An efficient method for solving sound propagation in range-dependent ocean waveguides was found

False killer whales use acoustic squint to target prey
Hunting in the ocean's murky depths, vision is of little use, so toothed whales and dolphins (odontocetes) rely on echolocation to locate tasty morsels with incredible precision. View More (2012-03-22)
Koalas' bellows boast about size
Koalas have a well-earned reputation for being dopey. Sleeping 19 hours out of every 24, and feeding for 3 of the remaining 5 hours, there doesn't seem to be much time for anything else in their lethargic lifestyle: that is until the mating season. View More (2011-09-29)
Critters on Ocean Floor Communicating in Synchronized Rumbles
Understanding animal communication has long been a fascinating and vast area of research for those who dare to welcome the challenge. Some species use body language to express their message while others use calls and loud noises. In fact, some animals communicate in frequencies that are inaudible to humans, either above or below our hearing range. View More (2011-09-09)
Caltech engineers develop 1-way transmission system for sound waves
While many hotel rooms, recording studios, and even some homes are built with materials to help absorb or reflect sound, mechanisms to truly control the direction of sound waves are still in their infancy. View More (2011-07-27)
New sound synchronization technology holds the key to earlier diagnosis of heart disease
Innovative UK technology is contributing to the development of a revolutionary digital stethoscope that could make it easier for GPs to spot the first signs of heart disease. View More (2011-06-03)
Noise research to combat 'wind turbine syndrome'
University of Adelaide acoustics researchers are investigating the causes of wind turbine noise with the aim of making them quieter and solving 'wind turbine syndrome'. View More (2011-06-01)
Force of acoustical waves tapped for metamaterials
A very simple bench-top technique that uses the force of acoustical waves to create a variety of 3D structures will benefit the rapidly expanding field of metamaterials and their myriad applications-including "invisibility cloaks." View More (2011-04-06)
How long does a tuning fork ring?
From the wooden bars in a xylophone or the head of a drum, to the strings and sound box of a guitar or violin, musical instruments are the most familiar examples of mechanical resonators. View More (2011-03-09)
Korean researchers reveal new sea defense model
Military tension between North Korea and the Republic of Korea (South Korea) extends to areas of the Yellow Sea. View More (2011-01-19)
Listening for ocean spills and their ecological effects
Scientists who study acoustics (the "science of sound") have over the years developed a variety of techniques to probe the hidden depths of oceans. View More (2010-11-17)
Army-funded technology detects bacteria in water
To keep soldiers in the battlefield healthy, the U.S. Army is exploring new ways to detect harmful bacteria in water. View More (2010-11-11)
Measurement scientists set a new standard in 3-D ears
Scientists at the UK's National Physical Laboratory (NPL) have developed a means of representing a 3D model ear, to help redefine the standard for a pinna simulator (the pinna is the outer part of the ear) - used to measure sound in the way we perceive it. View More (2010-10-13)
Lone whales shout to overcome noise
Just like people in a bar or other noisy location, North American right whales increase the volume of their calls as environmental noise increases; and just like humans, at a certain point, it may become too costly to continue to shout, according to marine and acoustic scientists.

NRL-SSC Scientists Investigate Acoustics in Gulf of Mexico
Scientists from the Naval Research Laboratory at Stennis Space Center, MS, (NRL-SSC) and Washington, D.C., recently completed an investigation of the acoustic properties of the deep seafloor in the Gulf of Mexico. View More (2010-05-13)
NC State Research Advances Voice Security Technology
Most people are familiar with security technology that scans a person's handprint or eye for identification purposes. Now, thanks in part to research from North Carolina State University, we are closer to practical technology that can test someone's voice to confirm their identity. View More (2010-03-09)
New 'hearing' maps are real conversation starters
Innovative sound-mapping software based on human hearing has been developed to help architects design out unwanted noise. View More (2010-03-08)
Leaves whisper their properties through ultrasound
The water content of leaves, their thickness, their density and other properties can now be determined without even having to touch them. View More (2010-02-04)
