- Two large sound installations, developed by transdisciplinary sound art and research group Urban Sound Institute, created a meeting place for one year of artistic and pedagogic activity in a Swedish regional museum. The project involved a historic sound archive, a string quartet, a local radio station, pedagogic workshops, several schools, children’s groups and musical education programs. The installations created a complexity of interior spaces, and acted as huge musical instruments to be ‘played’ by professional musicians, dancers and visitors. Through advanced computer programming and careful composition, modeling and distribution of sounds as words, narratives, music, space, bodily experiences and memory, the Sound Labyrinth allowed for great variations, durability over time, and different forms of interaction. The article describes the project, and discusses the exhibition as a platform for collective, multiple interaction; as an expanded musical-architectonic composition; and as a contribution to artistic research methodologies relevant for sound spaces within so-called sound-making disciplines.

- The research question is: “How to develop and apply acoustic artifacts and design methodologies for improving soundscapes in urban outdoor spaces?” In the project, this research question is limited to two specific types of urban outdoor spaces – city-park and city-square – and to two types of acoustic design artifacts. These are: I. Dynamic promotion of qualitative site specific sounds (e.g., the overall site specific sonic atmosphere, sounds from human activities, birds and fountains), which creates an improved soundscape. II. Sound-art installations, that creates delimited auditory sub-spaces within the park/square. The purpose and method is: 1. To provide two case-studies of artistic soundscape improvement, one in a noise polluted city-park and one in a city-square. The case-studies will serve as models for future applications of the new acoustic design artifacts. 2. To create and validate an innovative acoustic design methodology based on state-of-the-art real-time acoustic simulation tools integrated into the design process. The methodology will be validated in psychoacoustic listening experiments and field studies. 3. To determine the potential of the two acoustic design artifacts (I Dynamic promotion of qualitative site specific sounds, and II Sound-art installations) for providing pleasant and restorative soundscapes, in order to strengthening the social interaction as well as the spatial and aesthetical qualities in noise polluted city parks/squares. The present project beats a new track by combining acoustic design with sound art research, integrating methodologies based on real-time acoustic simulation and application of psychoacoustic methodology for validating simulations and for evaluating perceptual, emotional and behavioural effects on visitors to public open spaces. The ongoing research project, financed by the Swedish Research Council, is executed by the University College of Arts, Crafts and Design (Konstfack), Gösta Ekman Laboratory – Stockholm University and Karolinska Institutet and the Interactive Institute, all in Stockholm, Sweden.

- Noise is steadily on the rise in urban settings, creating a potential health hazard as well as being a nuisance. In major European cities, noise levels are so high that the majority of urban parks can no longer truly serve as recreational environments, a problem the WHO and the EU are attempting to address. This study explores various strategies that promotethe sustainable development of urban soundscapes at locations meant for rest, recreation, and social interaction. How are people affected by the combined effects of traffic and nature sounds in urban parks? To this end, we adopted a new track – the use of interdisciplinarymethodology – bringing together architectural analysis and artistic experiments, along with psychoacoustic methodology to evaluate aesthetic, emotional, perceptual, and spatial effects. A large-scale case study was conducted at a city park to explore if and how subjects are affected by purposely distributed sounds. The working hypothesis was that it is possible to cancel out traffic noise by affecting aural perceptions using a process known as informational masking. Our long-term objective is to create a scientific foundation for action plans, both pre-emptive and trouble-shooting, targeting parks and other similar public spaces that provide a relaxing environment.

Acoustic design in Commercial Space

Ingår i: ICSV13 Proceedings.
-
Konferensbidrag (refereegranskat)abstract
- The starting point for this paper is to discuss and challenge the visual dominance in architectural thinking, and to raise competence among architects and planners on sound and sound environment issues. To promote a sustainable urban environment,sounds must be integrated in the complexity of urban design and development. Therefore,it is especially important to integrate acoustic and architectural analysis.The paper focuses on urban public space as well as indoor public pathways, communication space and semi-public commercial space, e.g. shopping malls, wherereliability on sonic orientation may be crucial. For these kinds of collective spaces, I argue, it is especially important to integrate acoustic and architectural analysis. Their sonic conditions are often loud, blurred, and confusing, with little correspondence between visual and aural perception, and with weak articulations of spatial dimension, distance, borders, and orientation. If not cared for, the result may be increasing sound disturbance, lack of people’s moving through the areas, dangerous differences between day and night use, disorientation for several user groups, and segregation.The paper is integrated in the ongoing research project, Transmission, executed by Urban Sound Institute (USIT), financed by Swedish Research Council. Results will hopefully deliver good examples and operative methods to be used by architects, planners and acousticians. The paper is also a result of ongoing projects and research at the acoustic consultancy company Ingemansson Technology AB, Sweden

Akustiskt designlaboratorium
- 2006
-
Rapport (populärvet., debatt m.m.)abstract
- Projektets målsättning är att etablera ett Akustiskt Designlabb på Konstfack som ska omfatta utbildning och forskning, och även fungera som mötesplattform för representanter från näringslivet och från universitetssfären. Idag finns audioteknisk utrustning utspridd på Konstfacks olika institutioner. Tanken är att skapa ett interdisciplinärt labb genom att samla teknik och specialistkompetenser under ett och samma tak. Personalen kommer att bestå av ett team av personer med kunskaper om ljudredigeringsteknik, ljudkonstinstallationer, ljuddesign, rumsakustik, konst, arkitektur, musik och pedagogik mm. Teknik och kompetens ska vara tillgänglig för forskningsprojekt och för lärare och studenter vid de olika institutionerna, och även för skolans utställningsverksamheter. Det finns idag inget motsvarande ”laboratorium” i Sverige, utan det här skulle bli unikt för Konstfack.

Modelling the shopping soundscape

Ingår i: Journal of Sonic Studies. - Leiden : Leiden University Press. - 2212-6252. ; 1

Tidskriftsartikel (refereegranskat)abstract
- This article’s pivotal theme is: “How to compose a site-specific sound-art installation for a commercial space in order to improve conditions, while taking perceptual, social, aesthetical, temporal and spatial criteria into account” The interdisciplinary, art-based research approach is derived from the concept of acousmatics, i.e. the process of apprehending any sound, the source of which is invisible. Acousmatic perception concerns the everyday identification process; when lacking visual contact with the sound source, we automatically seek references, such as social (what produces the sound and what is my relation to it?), aesthetical, spatial and temporal (e.g. orientation and demarcation). The acousmatic concept identifies phenomena based on individually, culturally and spatially conditioned experiences. Today, a shopping culture dominates urban space. Indoor malls expose us to all types of acousmatically perceived sounds: jingles, signals, music and muzak from public loudspeakers, mobile devices, etc. In this respect, one could claim that the soundscape of the shopping culture embodies an acousmatic environment. In 2009, the research and sound-art group Urban Sound Institute (USIT) created a permanent sound installation in a shopping mall (Gallerian) located in downtown Stockholm. This installation serves as a case study for the present paper. The artistic assignment involved the creation of a meeting place without material devices as well as the enhancement of the overall atmosphere. The research objective was to elucidate different qualities of the sound installation in regard to the acousmatics of the shopping mall, promoting discussions on the articulation of sound-space configurations in relation to time and site-specific context, issues on musical-architectural qualities as well as objective, subjective and inter-subjective interrelationships between the experience of the sound-art installation and the experience of the shopping mall soundscape. Other applied, interrelated concepts are metabolic environment and masking- and cutting effects.

Noise design : Architectural Modelling and the Aesthetics of Urban Acoustic Spase
- 2003

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Noise Design takes up a structural approach to sound issuesin general and more particularly to urban acoustic space. Whilemost recent research efforts in the field adopt a defensiveattitude by seeking to protect people from sounds, this bookcelebrates our constructive and creative relations with thesound world and develops methods to manage sounds as mediatorsof qualitative information. The title is chosen to oppose thecommon meaning of noise, as‘unwanted sound’, whichimplies a denial of all its immanent qualities as well as itscontexts and uses. The thesis explores the concept oftransparent and fluid space as a central principle forarchitectural conception. Urban acoustic space is seen astransient and immaterial, making public and private spaces lesspredictable, less monotonous.The thesis comprises a Prologue, which provides an overviewof the subject, and three essays: On Sound Design, On SoundEffect and On Sound Identity. The first essay derives mainlyfrom the fieldof music, and discusses the internal,morphological properties of sound as well as aspects ofperception and notation. The second and third essays originatefrom theories and methods that are developed at the CressonInstitute in Grenoble, focusing on the external properties ofsounds, mainly regarding spatial, social and perceptualcriteria. Each essay comprises a descriptive and operativesection, whereby the former emphasises the exploration andqualification of conceptual tools, while the latter examinesthe concepts in different types of models. Thus, the essays arebased upon a research-by-design methodology, revealing theclose connection between analysis and creation towards design,and including, for example, the sound art installations Tiksand Tiger, which are presented in the text body and on theattached CD.Keywords:architecture, music, aesthetics, sound art,acoustic space, sound design, sound effect, sound identity,sound morphology, graphic notation, diagram, sampling culture,acousmatics, sound-object, metabolic effect, ubiquity,synecdoche, schizophonia, gesture,listening-hearing-attending-understanding, Cresson,Jean-François Augoyard, Pascal Amphoux, Tiks, Tiger.

Konferensbidrag (refereegranskat)abstract
- In an ongoing research project the design of acoustical atmospheres in large indoor spaces are investigated. The research question is: “How to redesign one sonic atmosphere into a variation of sub-atmospheres in large indoor spaces?” This question is especially valid for spaces such as semi-public commercial spaces (e.g. shopping malls), libraries, airports and communication spaces. The sonic atmosphere in these collective spaces is often loud, blurred and confusing, with little correspondence between visual and aural perception, and with weak articulations of spatial dimension, distance, borders and orientation. Together the different sound sources within these spaces generate a sonic hubbub. Even though such spaces comprise of several types of activities, the sonic atmosphere is the same all over the place.Hence, this research project focuses on design of sonic variations of the atmosphere; i.e., site specific sounds that deal with qualities such as communication, comfort, orientation, identity and privacy. The objective is to develop and test an interdisciplinary design methodology, which comprises a number of co-related methods; e.g. acoustic measurements, architectural site analysis, as well as virtual modeling and representation (visual and acoustic) of the space. The main part of the project is the virtual modeling and representation. It connects software that handles architectural 3D-modelling (SketchUp) with the Catt-Acoustic software, used for prediction and auralization.The research project also includes a case-study, which comprises proposals for redesign of a congress centre (Scandic Infra City), situated north of Stockholm. The proposals –consisting of architectural elements, sound installations (additions of sounds) as well as acoustical measures – will be demonstrated in a virtual model. The presumed effect is a differentiation in terms of a variety of sonic sub-atmospheres within the congress centre. The methodology developed in the project is intended to function as a tool for design measures of large indoor spaces. It is an interdisciplinary tool in that it supports acousticians as well as architects. The case-study may serve as a pilot model for future applications of redesign of the sonic atmosphere in large indoor spaces.This paper is a result of a research project, executed by the acoustic consultancy company ÅF-Ingemansson and the University College of Arts, Crafts & Design (Konstfack), Stockholm. The project has funding from the White’s Foundation for research and ARKUS, a Swedish foundation for the improvement of qualifications within architecture.

- In a Nordic cooperation project the acoustical conditions in open-plan offices was investigated. Measurements have been carried out in five open plan offices accompanied with an inquiry gathering the subjective judgments by the staff. A program for the acoustical measurements was designed specifying how to perform the measurements and which type of parameters to measure. The acoustical parameters included in the measurements 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), background noise levels in occupied and unoccupied offices. In two of the offices are furbishment program was carried out. Measurements as well as questionnaire were accomplished after refurbishment. The effect on room acoustic parameters DL2 and DLf and on subjective judgments by the staff will be presented in this paper.

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.

Konferensbidrag (refereegranskat)abstract
- The aspect of sound as a design element in an architectural context has been discussed for a long time, but there are still today very few permanent projects put into practice. The functional use of acoustics is easily comprehended when utilized to reduce unwanted noise from roads, or when it is perfected to convey speech and music in concert halls. To add sounds to create a sense of space, use it as a quality or defining identity is however still an unexplored field of knowledge. Finding the right balance between creating a quality for the space with dynamics and variety, while still being sustainable over time is challenging. The paper presents theories, methods, findings and results from a large project including nine installations. The project concerns indoor sound installations in large public spaces in Stockholm including acoustic investigations, electro acoustic installations and composition of sound installations for the specific space. The method is both scientific and art-based. The sound design is used as a way of empowering site-specific functions and architectural themes, but also in some cases as a solitary intentional characteristic quality of the space.
