Sparrows, blackbirds and the great tit are all birds known to sing at a higher pitch (frequency) in urban environments. It was previously believed that these birds sang at higher frequencies in order to escape the lower frequencies noises of the urban environment. Now, researchers at the University of Copenhagen and the University of Aberystwyth have discovered that besides noise, the physical structure of cities also plays a role in altering the birds´ songs. Urban birds sing...

Power outages are a common occurrence in the Dominican Republic, and industrial noise pollution from emergency generators is a growing concern. One DC generator designer is using QuietFiber noise absorbing material to lower the decibel levels at the La Serena superstore in Higuey. Higuey, Dominican Republic (PRWEB) January 05, 2012 Installation of QuietFiber® noise absorbing material has been completed in the massive generator room of the newly constructed La Sirena superstore in the...

Nine out of 10 city dwellers may have enough harmful noise exposure to risk hearing loss, and most of that exposure comes from leisure activities. Historically, loud workplaces were blamed for harmful noise levels. But researchers at the University of Michigan found that noise from MP3 players and stereo use has eclipsed loud work environments, said Rick Neitzel, assistant professor in the U-M School of Public Health and the Risk Science Center. Robyn Gershon, a professor with the...

Model shows that signal clarity only improves if specific energy conditions are met Scientists have shown the energy conditions, under which a weak signal supplied to a physical system emerges as a stronger signal at the output thanks to the presence of random noise (a process known as stochastic resonance), in a paper that has just been published in EPJ B´. Stochastic resonance goes against the intuitive idea that where noise is present, the signal tends to fade. It occurs in...

Dyslexia affects up to 17.5% of the population, but its cause remains somewhat unknown. A report published in the Nov. 23 issue of the online journal PLoS ONE supports the hypothesis that the symptoms of dyslexia, including difficulties in reading, are at least partly due to difficulty excluding excess background information like noise. In the study of 37 undergraduate students, the researchers, led by Rachel Beattie of the University of Southern California, found that the poor readers...

A study by the University of the Americas (Universidad de la Américas Puebla) in Mexico and the Basque Institute for Agricultural Research and Development, Neiker-Tecnalia, highlights the fact that noise pollution has negative effects on songbirds in cities. The field work, carried out in urban parks in the Metropolitan Area of Puebla-Cholula (Mexico), reveals that the green zones most affected by noise have less bird species.  Among the birds better adapted to urban...
