The Pied Piper of Fish
Fishy noises could be the answer for improved reef fisheries management according to an international team of researchers. Some juvenile coral reef fish are attracted by sounds they would have heard while they were in the egg. By using these sounds, the fish can be led to artificial reefs where they will start new colonies. It may be possible in... view more... (2003-06-03)
Artificial noise saves energy
Against the background of climate change, how can xDSL systems function more energy-efficiently and cost-effectively? Scientists are providing a solution combining existing methods which network providers could implement immediately. view more (2009-06-25)
Acoustic noise contains valuable information
The proper processing of acoustic noise can provide a wealth of information. Geophysicists have used seismic background noise measurements to reconstruct the crustal structure under Southern California. view more (2006-12-08)
Tackling brake noise
The squeal of brakes is not just irritating and annoying, it damages cars and railway wheel squeal is a serious environmental concern, contributing significantly to inner city noise pollution. EUREKA project E! 2122 BRAKENOISE is tackling the friction-induced vibration that can cause such excessive undesirable noise. The project partners - Bosch,... view more... (2004-01-07)
Living close to a flight path may increase the risk of high blood pressure
Being subjected daily to the noise of aircraft flying overhead may be risk factor for high blood pressure, suggests research in Occupational and Environmental Medicine. view more (2001-11-09)
Noisy neighbourhoods not good for children's mental health
Noise from local roads and railways has a detrimental effect on children's mental health, shows research in Occupational and Environmental Medicine. Children born premature and/or of low birthweight seem to be more vulnerable, the research shows. The research team investigated the impact of environmental noise on over 1400 children aged 8 to 11 in... view more... (2002-05-27)
New rail damping device could pave the way for rail expansion
A rail damping device, which will reduce noise from railway tracks and make rail expansion a more desirable option, has been developed by scientists at the Institute of Sound and Vibration Research (ISVR) at the University of Southampton, and Corus Rail. A European patent for this damper has just been granted. Last month, drivers in London were... view more... (2003-03-26)
Aircraft noise associated with children's school performance in maths and reading
Aircraft noise seems to affect children's school performance in maths and reading, but social and economic factors also play their part. Research published in the Journal of Epidemiology and Community Health examined the National Standardised Scores (SATs) of around 11,000 primary schoolchildren coming up to the age of 11. The SATs test maths,... view more... (2002-01-15)
Noise measurement may boost cell phone performance
Researchers at the National Institute of Standards and Technology (NIST) and industry collaborators have developed improved methods for accurately measuring very faint thermal "noise"—caused by random motion of electrons—in electronic circuits. view more (2006-06-28)
Aircraft noise raises blood pressure even whilst people are sleeping, says study
Night-time noise from aircraft or traffic can increase a person's blood pressure even if it does not wake them, according to a new study published today in the European Heart Journal. view more (2008-02-13)
34 million euros-worth of peace and quiet
How can noise levels be reduced? It's a question being investigated by researchers all over the world. Noise is now generally recognized as a serious form of environmental pollution. According to a study by the Bavarian state ministry of the environment and the EU White Paper on "European transport policy for 2010", over 100 million... view more... (2003-12-01)
Artificial night lighting jeopardises the survival of sea life
Artificial night lighting can jeopardise the survival of sea turtles by obliterating environmental cues. Writing in the August issue of Biologist, Mike Salmon, of Florida Atlantic University, USA, explains how artificial coastal lighting disturbs female sea turtles' navigation to nest beaches and disorientates their hatchlings so that many fail to... view more...

Study supports the use of mechanical assistance for acute or chronic heart failure in high-risk patients
The success of long-term implantable ventricular assist devices (LVAD) or artificial hearts has led to their increased use in patients previously thought to be unsuitable for mechanical support. This study documents the shift in the demographic profile of patients in need of artificial hearts to a more high-risk group. Looking at clinical records... view more... (2004-11-10)
A good ear: Rats identify specific sounds in noisy environments
A study conducted on hundreds of rats could help us understand how the brain identifies specific sounds in a noisy environment. view more (2008-11-19)
Noisy faucets
If loud plumbing fixtures get on the neighbour's nerves, the responsible plumber has to pay. Acoustic quality seals ought to help, but they are rarely found on cheap fixtures. Researchers tested the noise emission levels of bargain products. view more (2004-10-25)
Blur's noise and distortion reversed
Errant pixels and blurry regions in a photo, whether digital or scanned, are the bane of photographers everywhere. view more (2009-07-09)
Role of noise in neurons
Addressing a current issue in neuroscience, Aldo Faisal and Simon Laughlin from Cambridge University investigate the reliability of thin axons for transmitting information. They show that noise effects in ion channels in the brain are much larger than previously assumed - meaning the fidelity of transmission is compromised. view more (2007-05-04)
The bitter side of sweeteners
Sewage treatment plants fail to remove artificial sweeteners completely from waste water. view more (2009-06-18)
NC State study shows bird population estimates are flawed
Most of what we know about bird populations stems from surveys conducted by professional biologists and amateur birdwatchers, but new research from North Carolina State University shows that the data from those surveys may be seriously flawed - and proposes possible means to resolve the problem. view more (2008-11-21)
New '1/f noise' discovery promises to improve semiconductor-based sensors
More sensitive sensors and detectors based on semiconductor electronics could result from new findings by researchers from the United States, Norway and Russia. view more (2007-05-10)
