1. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. LÄS MER
2. Acoustic Characterization of Catalyst
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER
3. FunkyBot : Robotrörelser styrda i takt av ljudsignaler
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In the following report, a study regarding the control of a dancing robot has been conducted. The study covers whether a robot’s movements can be controlled by a recurring and pacing audio signal at a given BPM, and how well it does so. LÄS MER
4. Development of a Low Noise Drone Propeller Using CFD Simulations
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. LÄS MER
5. Möjligheten för biologisk mångfald på bostadsgårdar : hur olika typologier av bostadsgårdar skapar förutsättningar för habitat som gynnar biologisk mångfald
Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Biologisk mångfald i staden är avgörande för flertalet livsviktiga funktioner. Dessa inkluderar omhändertagande av dagvatten, luftrening och minskning av buller. Stadens grönytor bidrar till ökat välmående hos människorna och synlig biodiversitet har en positiv inverkan på människor. LÄS MER
