1. DRONAR: Obstacle echolocation using ego-noise
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. LÄS MER
2. Loudspeaker-Room Correction of Conference Rooms
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In this Thesis a study on the subject on how to improve the overall sound quality within a room using signal processing, played back using a loudspeaker, was conducted. This is a subject that has gained attention during the recent years, with more and more consumer and professional products including it. LÄS MER
3. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. LÄS MER
4. Accuracy verification of GT-Power model and reduction of computational time
Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWLSammanfattning : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. LÄS MER
5. Removal of Noise from Speech - A case study of a construction machine
Master-uppsats, KTH/Teknisk akustikSammanfattning : This report proposes a solution to allow speech to enter a construction machine cabin while removing noise sources. Examples of noises sources include, engine noise, traffic or other construction activities. Survey of the possible methods to remove noise from speech was conducted, however, beamforming was the technique chosen. LÄS MER
