  • 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 ...

  • New annual acoustic award scheme

    The Association of Noise Consultants (ANC) has launched a new annual awards scheme, offering entrants the chance to win a state-of-the-art sound level meter, donated by Brüel & Kjær. During the conference, taking place on Tuesday 8th October in Birmingham’s Crowne Plaza hotel, this particular prize will be awarded to the winner of the Brüel & ...

  • 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 ...
