  • 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 ...

  • New tool to assess sustainability of transport noise reduction devices

    A new method of assessing the sustainability of noise reduction devices (NRDs) used in transport infrastructure, such as noise barriers or absorptive claddings, is presented in a recent study. The new set of specially designed sustainability criteria allows NRDs to be easily and accurately evaluated, its developers suggest. Noise reduction is a key part of the European Commission’s ...

  • ASTM E336 - 11 standard test method for measurement of airborne sound attenuation between rooms in buildings

    The main part of this standard uses procedures originally developed for laboratory measurements of the transmission loss of partitions. These procedures assume that the rooms in which the measurements are made have a sound field that reasonably approximates a diffuse field. Sound pressure levels in such rooms are reasonably uniform throughout the ...

  • Review finds Europe lacks the drive to reduce transport noise

    At the end of August, a three part review of implementation of the Environmental Noise Directive (END) was finally published. Research informing publication of the reports was largely undertaken last summer – and given the ongoing nature of noise action planning, information on the approach in England at least is out of date. While the reports do give a comparison of approaches across ...

  • 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 ...
