1. Absorption of Sound : On the effects of field interaction on absorber performance
Sammanfattning : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. LÄS MER
2. Studies in Sound Symbolism
Sammanfattning : This thesis investigates how the Swedish lexicon is structured with respect to sound symbolism, the productivity of phonesthemes and cross language similarities in certain areas of sound symbolism. The Swedish lexicon has been analyzed with emphasis on the sound symbolic properties of initial and final consonant clusters, and to a certain extent of vowels. LÄS MER
3. Robust Sound Field Control for Audio Reproduction : A Polynomial Approach to Discrete-Time Acoustic Modeling and Filter Design
Sammanfattning : This thesis is concerned with the design and analysis of robust discrete-time filters for audio equalization and sound field control in real reverberant environments. Inspired by methods in polynomial control theory, a unified framework for acoustic modeling and filter design is developed. LÄS MER
4. SOUnd-DRIven BIOtechnology
Sammanfattning : Ultrasound has been vastly applied in different areas such as medical imaging and the food industry, but not much attempt has been made to investigate its influence on microorganisms and its potential to be applied in microbial biotechnology. Previous studies show the potential of acoustic waves to increase biomass yield, production of secondary metabolites and enhanced enzyme-catalyzed reactions, probably due to improved mass transfer and cell retention.

5. Low Frequency Impact Sound in Timber Buildings : Simulations and Measurements
Sammanfattning : 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. LÄS MER
