Seats Helped Ancient Greeks Hear From Back Row
As the ancient Greeks were placing the last few stones on the magnificent theater at Epidaurus in the fourth century B.C., they couldn't have known that they had unwittingly created a sophisticated acoustic filter. View More (2007-04-05)
Sound understanding of indoor acoustics could make hearing easier
An innovative technique that, for the first time, accurately measures exactly how sound behaves in 'real-world' situations is now under development-and could improve acoustics in buildings ranging from concert halls to railway stations. View More (2006-09-08)
An efficient method for solving sound propagation in range-dependent ocean waveguides was found
The coupled normal mode method is a powerful approach for solving range-dependent propagation problems in underwater acoustics. View More (2012-04-10)
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)
Study Compares Sound from Exploding Volcanoes with Jet Engines
New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. View More (2009-04-09)
Acoustic Monitoring of Atlantic Cod Reveals Clues to Spawning Behavior
For decades researchers have recorded sounds from whales and other marine mammals, using a variety of methods including passive acoustic monitoring (PAM) to better understand how these animals use sound to interact with each other and with the environment. View More (2013-03-25)
Lasers Generate Underwater Sound
Scientists at the Naval Research Laboratory are developing a new technology for use in underwater acoustics. The new technology uses flashes of laser light to remotely create underwater sound. View More (2009-09-08)
'Smart stethoscope' advance in monitoring treatment of kidney stones
A new listening device, developed by scientists from the University of Southampton, is being used to monitor the effectiveness of the treatment of kidney stones - saving patients unnecessary repeat therapy and x-ray monitoring. View More (2012-12-13)
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)
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)
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)
NOAA: Underwater noise decreases whale communications in Stellwagen Bank sanctuary
According to a NOAA-led paper published today in the journal Conservation Biology, high levels of background noise, mainly due to ships, have reduced the ability of critically endangered North Atlantic right whales to communicate with each other by about two-thirds. View More (2012-08-16)
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)
The Secrets of Stradivarius

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)
It whistles; change in pitch tells all in this new sonic gas analyzer
Penn State researchers have developed a prototype sonic gas analyzer that automatically and continuously tracks the concentration of a gas in an air/gas mixture based on changes in pitch. View More (2005-10-20)
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)
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)
Thieving whale caught on video gives rare clues about hunting strategy, sound production
For decades scientists have been intrigued by the variety of sounds emitted by sperm whales, partly due to a popular theory that suggests that the sounds might contain information about the animals' size. View More (2009-05-22)
From neolithic bones to carbon fiber - flute-making gets boost from modern science
A combination of modern materials, technology, and venture capital catapults Finnish flute-makers in international music spotlight. Beauty of sound "I was inspired by the delicate sound of the simple bamboo flute and experimented with various materials and techniques to construct a light flute frame," Matti K'¤hönen of Matit Flutebrothers in Helsinki recalls his inspiration to experiment...
