1. Noise from wind turbines
Abstract : A rapid growth of installed wind power capacity is expectedin the next few years. However, the siting of wind turbines ona large scale raises concerns about their environmental impact,notably with respect to noise. READ MORE

2. Noise in the preschool : health and preventive measures
Abstract : This thesis is based on noise recordings and health evaluations carried out at preschools in the northern part of Sweden. Sound level recordings were made on individuals and by use of stationary devices in dining rooms and play halls. Health evaluations were based on ratings by use of questionnaires and by analyses of cortisol. READ MORE

3. Noise Aspects of some Si-based One Port Devices and Carbon Nanotubes
Abstract : The p-n junctions and Schottky diodes based on Si1-xGex and SiC are of great importance in modern electronic applications, such as microwave detectors and mixers. Carbon nanotubes (CNTs) have appeared recently as an attractive new class of materials with a reduced dimensionality, and proposed as building blocks for nanoelectronic technology. READ MORE

4. Sound propagation around off-shore wind turbines
Abstract : Low-frequency, long-range sound propagation over a seasurface has been calculated using a wide-angel Cranck-NicholsonParabolic Equation method. The model is developed toinvestigate noise from off-shore wind turbines. Thecalculations are made using normal meteorological conditions ofthe Baltic Sea. READ MORE

5. Acoustic excitation and transmission of lightweight structures
Abstract : In order to increase our knowledge of the sound transmission and radiation processes of lightweight wall and floor structures, theoretical models are needed. Detailed models may form a valuable tool. In lightweight floor structures, impact sound insulation is perhaps the most important property to consider. READ MORE
