  2. 21. A few aspects of aircraft noise

    Author : Crispin Dickson; Shafiquzzaman Khan; Mendel Kleiner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paired comparison; sorting based paired comparison; sorting algorithms; mergesort; quicksort; aircraft sound synthesis; aircraft noise; sound quality; tonal effects; angle positions; flight conditions; methods of equalization; cognition; Acoustics; Akustik;

    Abstract : A few aspects of aircraft noise were evaluated. These were (i) methods of subjective evaluations, (ii) effects of equalization and (iii) the effects of cognitive aspects.In the first paper, sorting algorithms were used instead of conventional paired comparison method in order to reduce the number of pairs in the evaluation of subjective judgments.

  4. 22. Indoor Environment and User Perception. A Field Study in a Hospital Ward

    Author : Jennie Skoog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indoor environment; thermal climate; hospital ward; indoor air quality; comfort; perception; sound; light;

    Abstract : The research on indoor environment has become more important and extensive the last decades. There is, however, a lack of studies made in buildings with two or more distinct groups of people. This study deals with hospital wards, which are a prime example of buildings occupied by more than one homogenous group of people. READ MORE

  5. 23. Ergonomics Methods and Work Procedures in Car Manufacturing for Improvement of Quality, Productivity and Health at Work

    Author : Ann-Christine Falck; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost-benefit; ergonomics; manufacturing; productivity; risk assessment; quality;

    Abstract : Many studies have concluded that there are great human and economic gains in finding ergonomically sound solutions as early as possible in product and production development. Hence, the objective of the research presented in this thesis was to evaluate methods for improved ergonomics assessment in early phases of product and production development and in production.

  6. 24. Low Frequency Impact Sound in Timber Buildings : Simulations and Measurements

    Author : Jörgen Olsson; Andreas Linderholt; Leif Kari; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-frequency; impact sound; light weight floor; timber joist floor; tapping machine; multi-storey timber building; frequency response functions.; Stegljud; Byggteknik; Civil engineering;

    Abstract : An increased share of construction with timber is one possible way of achieving more sustainable and energy-efficient life cycles of buildings. The main reason is that wood is a renewable material and buildings require a large amount of resources. READ MORE

  7. 25. Careful Convivial Listening : Making Sound Work Apparent as Political Action

    Author : Hugo Boothby; Tina Askanius; Bo Reimer; Salomé Voegelin; Malmö universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Care; Conviviality; Experimental Media; Listening; Sound Work;

    Abstract : Focusing on the creation and performance of sound work this doctoral thesis considers the value of listening as a site of political action. The meaning of sound work is dual; connoting both an artifact that is created and performed, a work of art, and the processes of creating sound, the work of listening. READ MORE
