Low frequency sound causes lesions in sensory organs of squid, octopus and cuttlefishNoise pollution in the oceans has been shown to cause physical and behavioral changes in marine life, especially in dolphins and whales, which rely on sound for daily activities. However, low frequency sound produced by large scale, offshore activities is also suspected to have the capacity to cause harm to other marine life as well. Giant squid, for example, were found along the shores of Asturias, Spain in...
HAMBURG, Germany, April 6, 2011 /PRNewswire/ -- - Amazingly Better Acoustics Aircraft noise is one of the biggest environmental concerns. But in the interior of aircrafts, passengers and the crew also have to be relieved from noise emissions. At the Expo 2011, the Pelzer Consult GmbH presented its worldwide novel aircraft trim panel that reduces the noise level in the interior by up to 10 decibels. The supplier of VIP aircrafts will be excited about it: Thanks to the...
Babies are born earlier when their mothers live near a concentration of freeways and main roads, a study of 970 mothers and their newborn babies in Logan City, south of Brisbane, has found.Senior research fellow Associate Professor Adrian Barnett from Queensland University of Technology's (QUT) Institute of Health and Biomedical Innovation (IHBI) said the study, published today in the online journal Environmental Health, showed that the more freeways and highways around a pregnant woman's...

Using underwater speakers to play noise at levels similar to those produced by recreational speedboats, the researchers found that three-spined sticklebacks exposed to even brief noise playback made more foraging mistakes and were less efficient at consuming the available food compared to those in quiet conditions.Dr Julia Purser, the study's lead author, said: "The fish appeared to be distracted by the addition of noise to their environment. Much as you or I might struggle to...
Whether on a battlefield, in a factory or at a rock concert, noise-induced hearing loss is one of the most common hazards people face.Researchers at Washington University School of Medicine in St. Louis have identified a low-dose, two-drug cocktail that reduces hearing loss in mice when given before they are exposed to loud noise. The drugs, already FDA-approved for other conditions, also treat hearing loss after noise exposure.While both drugs are known to protect hearing on their own, this...
