  • 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 ...

  • Protecting Workers from Hearing Lose Due to Excessive Noise Levels

    Worker exposure to environmental noise is sometimes difficult to avoid. However, understanding noise levels employees are exposed to is not difficult. The most significant effect of high noise levels is permanent hearing loss. Hearing loss and the degree of loss are directly related to the total energy impacting the ears. Often, the total energy at a noise source cannot be changed. In these ...

  • Green walls, effective acoustic insulation

    The Department of Thermal Machines and Motors of the University School of Mining and Public Works Engineering is exploring the energy efficiency of buildings by conducting tests on various materials. Zaloa Azkorra, an agricultural engineer, began to study the acoustic and energy efficiency of green walls to find out their performance, since these walls consisting of vegetation could be beneficial ...

  • Green walls show promise as sound barriers for buildings

    Green walls, designed so they are covered in vegetation, could help cut the amount of noise that enters buildings, a new study has found. In lab. tests, researchers found that a modular green wall system reduced sound levels by 15 decibels (dB). This leads them to believe that it is a promising sound reduction device that could improve quality-of-life for city residents. Green walls and green ...

  • 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 ...

  • Air Compliance Testing Now Offers FTIR

    Commonly referred to as FTIR, Fourier Transform Infrared Spectroscopy is the most recent addition to the Air Compliance Testing technological toolbox. FTIR can be used to identify chemicals from paints, polymers, coatings, spills, drugs, and contaminants (qualitative analysis). FTIR is likely the most powerful tool for identifying types of chemical bonds (functional groups). The wavelength of ...

  • ASTM E1179 - 11 Standard Specification for Sound Sources Used for Testing Open Office Components and Systems

    This specification states the requirements for sound sources used for measuring the speech privacy between open offices or for measuring the laboratory performance of acoustical components. The sound source shall be a loudspeaker enclosed in a box that has a maximum dimension of 0.30 m (1 ft) on a side, to reduce spurious sound reflections. The measurements shall be carried out in a free ...
