- This paper will discuss the use of psychoacoustic evaluation as a tool for optimization of the soundscape simulator developed in the Listen project. The listen project is a three-year research project focused around developing a demonstrator, which auralizes the sound environment produced by road and railway traffic. The resolution of the parameter space of the simulator heavily influences the performance of the simulator. The perceptual resolution of the parameter space is investigated and the resolution is adjusted accordingly. The most important parameter is velocity. Adjustments of the resolution of this parameter alone gives a 60% reduction of the usage of memory.

Colour Research with Architectural Relevance : How Can Different Approaches Gain from each Other?

- Colour research from different scientific traditions start from different basic questions and use different methods and concepts. This makes it difficult to communicate and to Judge result relevance in a wider perspective. Here we start from architects' need of colour knowledge and discuss recent studies of colour appearance and colour emotion, with and without explicit connection to architecture. We stress the need for further development and clarification of concepts and conclude that the multitude of studies With different approaches con be seen os cases, jointly adding to a widened and deepened understanding of colour.

SYN-TES : human colour and light synthesis. Towards a coherent field of knowledge
- 2010

Ingår i: Colour and light in architecture. - Verona : Knemesi. - 9788896370049 ; , s. 235-240

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The research project SYN-TES aims at contributing to a theoretical development transforming the field of colour and light into a coherent field of research. This includes the identification of important problems and the development of theoretical and methodological tools for the trans-disiplinary understanding necessary to solving them. Special emphasis is put on the spatial interaction of colour and light in architecture. The work has the form of seminars/workshops where colour and light specialists from different academic disciplines (six Nordic universities) and companies (light sources, colorimetric standards, window glass) examine different aspects of the problem complex. Sub-projects deal with the epistemology and concepts of colour and light, with methods for analysing colour and light in existing architectural spaces and with the relationship between energy and light quality.

Acoustic design of open-plan offices
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The acoustic conditions in open-plan offices were investigated in a Nordic cooperation project. Measurements were carried out in five open-plan offices along with a questionnaire to gather the staff’s subjective judgments.A programme for the acoustic measurements was drawn up, specifying how to perform the measurements and which type of parameters to measure.The acoustic parameters included are Reverberation time T20, Early decay time (EDT), Clarity (C50), Speech transmission index (STI), Speech intelligibility index (SII), Privacy index (PI), Rate of spatial decay of sound pressure levels per distance doubling (DL2 ), Excess of sound pressure level with respect to a reference curve (DLf), and background noise levels in occupied and unoccupied offices.A refurbishment programme was carried out in two of the offices. Measurements were performed after refurbishment and a questionnaire was completed. It is concluded that parameters relating to sound propagation, such as DL2 and DLf, are appropriate for the acoustic evaluation of open-plan spaces.A refurbishment programme was carried out in two open-plan offices. It has been shown that DL2 and DLf are sensitive to the acoustic treatment carried out and that they also reflect an improvement in the subjective judgment as regards the acoustic environment in general. Moreover, these parameters can be converted into a (comfort) radius indicating the distance for achievement of a certain reduction of the sound level from a sound source.This application could serve as a practical tool for the acoustic planning of open-plan offices.
