  1. 1. Absorption of Sound : On the effects of field interaction on absorber performance

    Författare :Anna Färm; Mats Åbom; Ragnar Glav; Susann Boij; Gareth Bennett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; Porous absorbers; Bulk reaction; Local reaction; Boundary layer; Grazing flow; Temperature gradients; Surface impedance; Sound field; Pass-by noise; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. LÄS MER

  3. 2. Sound field separation with microphone arrays

    Författare :Elias Zea; Ines Lopez Arteaga; Mats Åbom; Leif Kari; Jean-Hugh Thomas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound field separation; Microphone arrays; Near-field acoustic holography; Reflecting surfaces; Railway rolling noise; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Sound field analysis is a fundamental tool in the design, manufacturing, testing and diagnosis of machines and transportation means, as well as the legislations that regulate noise levels in order to minimize environmental pollution. Customary solutions to the problem of sound field analysis are microphone array technologies such as near-field acoustic holography (NAH) and beamforming. LÄS MER

  4. 3. Noise design : Architectural Modelling and the Aesthetics of Urban Acoustic Spase

    Författare :Björn Hellström; KTH; []
    Nyckelord :architecture; music; aesthetics; sound art; acoustic space; sound design; sound effect; sound identity; sound morphology; graphic notation; sampling culture; acousmatics; metabolic effect; schizophonia;

    Sammanfattning : 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.

  5. 4. Designing with Urban Sound : Exploring methods for qualitative sound analysis of the built environment

    Författare :Nina Hällgren; Katja Grillner; Björn Hellström; Gunnar Sandin; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Architectue; urban sound design; urban sound planning; soundscape; urban planning; artistic research; architectural research;

    Sammanfattning : The licentiate thesis Designing with Urban Sound explores the constitution and qualitative characteristics of urban sonic space from a design-oriented and practice-based perspective. The act of lifting forth and illuminating the interaction between architecture, the creation of sound and a sonic experience aims to examine and develop useful tools and methods for the representation, communication and analysis of the exterior sonic environment in complex architectural spaces.

  7. 5. Before Sound: Transversal Processes in Site-Specific Sonic Practice

    Författare :Åsa Stjerna; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; sound installation; site specific; site specificity; sound art; artistic research; philosophy of immanence; assemblage; affect; ethics; public space; transversality; transversal; Gilles Deleuze; Félix Guattari; sonification; sound design; sonic practice; transformation;

    Sammanfattning : This doctoral research explores the capacity of site-specific practices of sound installation to bring about transformation. It claims that in order to understand this capacity, we need to address the complexity of the transversal processes that make up artistic practices in this field, and understand that these transversal processes in fact precede sound.
