  • Urban greening reduces noise pollution

    Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise. The Environmental Noise Directive (2002/49/EC)1 ...

  • Silencing nuisance noise with an acoustic cloak

    Noise pollution is a key issue facing policy makers in urban areas. In a recent development that might help town planners, researchers have proposed a design for a new sound-proofing device, an acoustic 'cloak', that could be 100 per cent effective. This suggests that, one day, buildings could be adapted to fully protect their inhabitants from external noise. An acoustic cloak is capable of ...

  • HATS off for raising noise awareness

    As part of Noise Action Week, East Hampshire District Council's (EHDC) Environmental Health team offered residents the chance to find out if their love of loud music is permanently damaging their ears.

  • Gadget Watch: Noise reduction in new Sony phone

    I typically have headphones on when I'm home in New York, whether it's during a jog or a commute. I often crank the volume up, at the risk of hearing loss, so that I could hear my favorite podcasts over loud subways and honking cars. I was excited to see noise-cancelling technology in Sony's new Xperia Z2 smartphone. I've resisted investing in pricey noise-cancelling sets because I'm prone to ...
