In the frame of the SOPRANOISE project (funded by CEDR in the Transnational Road Research Programme 2018) the database of the European noise barrier market developed during the QUIESST project was updated with newly acquired data. This database gives the opportunity for an empirical study on the correlation between the different measurement methods for the acoustic properties of noise barriers (according to the EN 1793 series) to further investigate the interrelationships between these methods by using single-number ratings and third-octave band data. First a correlation of the measurement methods for sound absorption under diffuse field conditions (EN 1793-1) and sound reflection under direct sound field conditions (EN 1793-5) is presented. Secondly, a correlation of the measurement methods for airborne sound insulation under diffuse field conditions (EN 1793-2) and airborne sound insulation under direct sound field conditions (EN 1793-6) is shown. While for airborne sound insulation a distinct correlation is found due to the wide data range, for sound absorption no robust correlation can be found.

A Performance

This study aims to build a performance measurement system of zakat institutions from the perspective of maqashid sharia and sharia enterprise theory. This study embarks from previous studies focusing on the performance measurement methods applied to the zakat institutions. Understanding of maqashid sharia in this paper refers to the concept formulated by Al Ghazali and Ibn Ashur. Their applications in contemporary research can be found in various studies. This paper concludes that performance measurement based on maqashid sharia for Islamic bank can be used by zakat institution, by making various adjustments according to the characteristics of zakat institutions. In addition, this study also designed a performance scorecard to assess the performance of zakat institutions based on the perspective of maqashid sharia and sharia enterprises theory. From the scorecard, the zakat institution can calculate the zakat management index from a broader perspective.
