  • EA: Four new materials set for quality protocols project

    The Environment Agency has announced the four new materials that will form part of its Quality Protocols project which aims to define end-of-waste criteria for waste streams. The four materials are the following: Treated ash from the incineration of poultry litter, feathers and straw, which can be re-used as a fertiliser, substituting inorganic fertilisers; Non-virgin wood from ...

  • We’re hearing work-related noise issues, loud and clear

    While awareness of how exposure to harmful dust in the workplace is on the increase, as are the methods for effectively monitoring this, the ongoing problem of noise induced hearing loss, as the global number one preventable occupational disease cannot be ignored. According to a recent article issued by North America’s National Institute of Occupational Health and safety (NIOSH) hearing ...

  • 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 ...

  • Effects of Noise on Bar, Pub and Nightclub Workers

    Since music and entertainment noise is generally regarded as desirable as opposed to undesirable noise, it tends to be overlooked compared to noise in other industries. However, a 2004 TUC/RNID health and safety report revealed that bar, pub and nightclub workers such as bar tenders, performers or security staff are regularly exposed to as high as 110dB(A), which is equivalent to being within ...

  • 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 ...
