1. Market for Reuse - Investigating reuse of acoustic ceilings from a market perspective
Master-uppsats, Lunds universitet/ProduktionsekonomiSammanfattning : Context: Today, 96% of Sweden’s materials come from virgin resources and only 3.4% of resources used in Sweden are retained in the value chain. From a total of 266 million tonnes fed into the economy each year, 46.9% consist of construction materials. LÄS MER
2. Two-dimensional Acoustic Localizer : Proof of concept study for an acoustic surveillance device
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och systemSammanfattning : Public surveillance is evolving with the progress in technology and with it the fear of privacy breach, the feeling of being watched at all times. This thesis aimed to serve as a proof of concept (POC) for a new type of acoustic based surveillance for localizing gunshots in urban environments. LÄS MER
3. Assessing indoor environmental quality and occupant comfort in modern wood buildings with post-occupancy evaluation and building performance simulation
Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : The European building sector is a source of significant negative environmental impacts, and large part of its carbon emissions can be attributed to heating, cooling and lighting of buildings – in other words, regulating buildings’ indoor environments. As people spend most of their lives indoors, there is a great challenge to create comfortable indoor environments, while also striving for further energy-efficiency and lower environmental impact.

4. What's Next in Sustainable Acoustic Materials?
Master-uppsats, Lunds universitet/InnovationSammanfattning : As industries have begun to rethink the way they design, make and dispose of products for the purpose of sustainable development, manufacturers of acoustic products have been slow off the mark. The majority of acoustic products are still made of primarily virgin material made from petrochemical resources, which have a significant impact on the environment. LÄS MER
5. Modeling and Compensation of Nonlinear Distortion in High Efficient Electrodynamic Loudspeakers
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Signaler och systemSammanfattning : Loudspeakers transform electrical energy into acoustic waves but most of the electrical energy is lost as heat. It is possible to increase the electro-acoustic efficiency by changing the electrical, mechanical or acoustical design of the loudspeaker but with these changes come unwanted side effects. LÄS MER
