Considerations for the perceptual evaluation of steady-state and time-varying sounds using psychoacoustic metrics

Sound evaluation based on listening experiments is very costly and time-consuming. Alternatively, the sounds under evaluation can be compared using psychoacoustic metrics, under the hypothesis that sounds that differ by more than one just-noticeable difference (JND) are perceived as significantly different from each other. Wellestablished...

Creating the Business Case for the Zero Energy Refurbishment of Commercial Buildings

Net zero energy is already an ambitious target for several buildings, especially since the DIRECTIVE 2010/31/EU that requires increasing the number of nearly zero-energy buildings. The existing commercial building stock needs to be included, in order to achieve the 2020 EU environmental targets. The main barriers of zero-energy refurbishment of...
