  2. 16. 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

  4. 17. Bone conducted sound transmission for communication systems

    Author : Sabine Reinfeldt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone conduction; sound field hearing; occlusion effect; transcranial transmission; communication system; bone conduction microphone; hearing protection devices; hearing;

    Abstract : Bone conducted (BC) sound is vibrations in the skull bone that are transmitted to the cochlea and perceived as sound, originating from a sound field or a vibration transducer. This transmission path can be advantageous for communication systems in some situations, e.g. READ MORE

  5. 18. Predicting the sound field from aeroacoustic sources on moving vehicles : Towards an improved urban environment

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pass-by simulations; aeroacoustic sources; urban sound propagation; direct numerical beamforming; linear programming deconvolution; Kirchhoff approximation; moving sources; detached-eddy simulation; Ffowcs Williams-Hawkings; vehicle design; förbifartssimuleringar; aeroakustiska källor; urban ljudutbredning; direkt numerisk lobformning; avfaltning med hjälp av linjärprogrammering; Kirchhoffs approximation; rörliga källor; detached-eddy simulation; Ffowcs Williams-Hawkings; fordonsdesign; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : 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. READ MORE

  6. 19. 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. 20. 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
