  1. 1. Masking of wind turbine sound by ambient noise

    Author : Karl Bolin; Mats Åbom; Sten Ljunggren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Abstract : The main objective of this work was to gain an increasing understanding of the properties of vegetation noise and also to the relative ratios of different natural ambient noises to mask wind turbine sound. A discrete vegetation noise model was developed and compared to an earlier model showing improved estimations, especially at frequencies below 0. READ MORE

  2. 2. Wind Turbine Noise and Natural Sounds : Masking, Propagation and Modeling

    Author : Karl Bolin; Mats Åbom; Jens Forssén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind turbine noise; models of natural sound sources; masking; Acoustics; Akustik;

    Abstract : Wind turbines are an environmentally friendly and sustainable power source. Unfortunately, the noise impact can cause deteriorated living conditions for nearby residents. The audibility of wind turbine sound is influenced by ambient sound. This thesis deals with some aspects of noise from wind turbines. READ MORE

  3. 3. Wind Turbine Sound in Cold Climates

    Author : Kristina Conrady; Anna Rutgersson; Karl Bolin; Sabine von Hünerbein; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric acoustics; wind turbine sound; outdoor sound propagation; cold climates; Meteorology; Meteorologi;

    Abstract : The increase in the number of wind turbines (WTs) in populated areas in cold climates increases the number of people potentially being affected by WT sound. Outdoor sound propagation is strongly dependent on meteorological conditions, however, limitations in the knowledge exist regarding the implications of meteorological conditions in cold climates.

  4. 4. Final Approach : Measurements and Ratings of Aircraft Landing Noise

    Author : Anders Johansson; Karl Bolin; Susann Boij; Antonio Filippone; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft noise; acoustic measurements; psycho acoustics measurements; noise annoyance; Flygplansbuller; akustiska mätningar; psykoakustiska mätningar; bullerstörning; Teknisk mekanik; Engineering Mechanics;

    Abstract : Följande avregleringen av flygmarknaden har flygtrafiken ökat snabbt sedan mitten av 1990-talet. Detta har oundvikligen lett till en utbyggnad av flygplatser, vilket på många platser runt om i världen har lett till oro och konflikter på grund av ökade bullernivåer. READ MORE

  5. 5. Generational Use of News Media in Estonia : Media Access, Spatial Orientations and Discursive Characteristics of the News Media

    Author : Signe Opermann; Göran Bolin; Cecilia von Feilitzen; Cristina Ponte; Södertörns högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; generation; media use; media repertoires; media landscapes; news consumption; age; life course; social space; Estonia; Kritisk kulturteori; Critical and Cultural Theory; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Contemporary media research highlights the importance of empirically analysing the relationships between media and age, changing user patterns over the life course, and generational experiences within media discourse beyond the widely hyped buzz terms such as the ‘digital natives’, ‘Google generation’, and other digitally and technologically capable generation groups. This doctoral thesis seeks to define the ‘repertoires’ of news media that different generations use to obtain topical information and create their ‘media space’. READ MORE
