  2. 1. Healthy Offices: Conceptualizing Healthy Activity-based Offices

    Author : Melina Forooraghi; Chalmers tekniska högskola; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salutogenic; Workplace; Office design; Case study; Activity-based office; Sense of coherence; Health; Well-being;

    Abstract : This thesis explores the interrelations between the design characteristics of activity-based offices, users’ perceptions of them, and users’ sense of coherence. The goal is twofold: (i) contribute to conceptualizations of healthy activity-based offices and (ii) facilitate practical use of the sense of coherence theory for office designers. READ MORE

  4. 2. Computational analysis and design optimization for acoustic devices

    Author : Abbas Mousavi; Eddie Wadbro; Martin Berggren; Niels Aage; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; computational analysis; viscothermal acoustics; material distribution topology optimization; acoustic black holes; finite element method;

    Abstract : This thesis focuses on material distribution topology optimization for acoustic waveguides. The limitations of the material distribution approach are discussed in the context of acoustic waveguides with extensive viscous and thermal boundary losses. READ MORE

  5. 3. Sound Field Design for Transducer Array-Based Acoustic Levitation

    Author : Carl Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear Acoustics; Sound Field Design; Transducer Arrays; Acoustic Levitation; Numerical Optimization;

    Abstract : Acoustic levitation is a technique where sound waves are used to hold an object at a designated position, suspending it against other external forces and keeping it stable in the desired position. Transducer arrays are an arrangement of many loudspeaker elements, tuned such that the array creates a sound field that is too complicated for the individual elements to produce on their own.

  6. 4. On the ECO2 multifunctional design paradigm and tools for acoustic tailoring

    Author : Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Per Wennhage; Franck Sgard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle design; planned obsolescence; anisotropy; porous materials; sound absorbing materials; acoustic modelling; power balance; energy assessment; dissipated power.; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Nowadays vehicle design paradigm influences not only the effectiveness of the different means of transport, but also the environment and economy in a critical way. The assessment of the consequences that design choices have on society at large are necessary to understand the limits of the methods and techniques currently employed. READ MORE

  7. 5. Toward a poetics of fibre art and design : aesthetic and acoustic qualities of hand-tufted materials in interior spatial design

    Author : Kaja Tooming; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Fibre art; acoustics; interior design; hand tufting;

    Abstract : This inquiry explores the aesthetic and acoustic qualities of fibre art and design. The goal is to understand how the manner of hand tufting, the selection of fibre materials, and the creation of two- and three-dimensional forms can work together to solve problems of interior design...
