4. 23. The effects of distortion : Investigating how different types of distortion affect timbral attributes and subjective preference

   Kandidat-uppsats, Luleå tekniska universitet/Medier, ljudteknik och teater

   Författare :André Waldton Lézin; [2020]
   Nyckelord :distortion; subjective; subjectivity; preference; perception; timbre; roughness; warmth; descriptors;

   Sammanfattning : The effects of distortion has been investigated prior to this study, however most of these studies focus on the objective physicalities of a certain type of distortion or they might apply distortion in static amounts to examine effects of loudspeaker distortion. Objectively the varying types of distortion may be different, however there are little explanations on how these types subjectively might sound different. LÄS MER

5. 24. Sound ranging using multilateration and Kalman filter

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Tobias Samuelsson; [2020]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Sound ranging is a method to locate sources of sound waves using microphones or other types of receivers at known reference positions. Nowadays, these receivers can be made both very small and powerful, lasting for a long time on a single battery charge, making them suitable for longtime outdoor purposes such as detecting artillery fire or other loud sounds.
