1. 1. 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.

3. 2. 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.

4. 3. Urban Sound Planning - An attempt to bridge the gap

   Författare :Laura Estévez Mauriz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prediction methods; road traffic noise; traffic dynamics; Urban sound planning; quiet side; urban systems; citizen participation; urban strategies;

   Sammanfattning : Cities are constantly between transition and adaptation, where current urban development needs a consistent strategic solution capable of understanding and including the relationships between urban form, environment and urban life. Awareness of the quality of the urban environment is leading the vision on the resilience and sustainability of the built environment, highlighting the importance of a multidisciplinary urban framework.

   Sammanfattning : In a society where environmental noise is becoming a major health and economical concern, sound emissions are an increasingly critical design factor for vehicle manufacturers. With about a quarter of the European population living close to roads with heavy traffic, traffic noise in urban landscapes has to be addressed first. LÄS MER

7. 5. Sound propagation from sustainable ground vehicles : from aeroacoustic sources to urban noise

   Författare :Nicolas Pignier; Ciarán O'Reilly; Susann Boij; Gwenael Gabard; KTH; []

   Sammanfattning : Transportation is the main source of environmental noise in Europe, with an estimated 125 million people affected by excessive noise levels from road traffic, causing a burden of noise related diseases and having a substantial economic impact on society. In order to reduce exposure to high levels of traffic noise, two approaches are the topic of extensive research: preventing sound from propagating from roads and railways using for example noise barriers, and reducing the sources of noise themselves.
