11. Factors Governing Acoustical Comfort In Vehicle Compartments
Abstract : A pleasant interior sound field is an essential comfort criterion for vehicle occupants.The pleasantness is mainly influenced by a low overall sound pressurelevel. Further minimization of driving noise, however, is constricted on thelower end by physical limitations. READ MORE

12. Aeroacoustic Prediction for Vertical Axis Wind Turbines
Abstract : This thesis investigates the aerodynamic and aeroacoustic prediction of vertical axis wind turbines, using computational fluid dynamics simulations. Noise pollution from wind turbines is one of the disadvantages of wind energy, calling for strategies to reduce noise levels. READ MORE

13. Investigation of perforated mufflers and plates
Abstract : Mufflers are used in for instance exhaust system of cars or trucks to reduce noise. Perforated pipes are one of the main components of modern mufflers. To study acoustic properties of mufflers with perforated pipe is one of the main targets of this thesis. READ MORE

14. Emergence of words : Multisensory precursors of sound-meaning associations in infancy
Abstract : This thesis presents four experimental studies, carried out at the Phonetic laboratory, Stockholm University, on infants’ ability to establish auditory-visual sound-meaning associations as a precursor of early word acquisition. Study I reports on the effect of linguistic variance on infants’ ability (3- to 20-months) to establish sound-meaning associations. READ MORE

15. Affect as a Component of Perceived Sound and Vibration Quality in Aircraft
Abstract : The concept of product sound quality is becoming an integral component of product development and design. The research presented in this thesis test the notion that affective reactions (i.e. positive-negative feelings) are a major determinant of perceived sound quality. READ MORE
