    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Yasser Alsouda; [2019]
    Keywords : urban noise; sound pressure level SPL ; internet of things IoT ; machine learning; support vector machine SVM ; k-nearest neighbors KNN ; bootstrap aggregating Bagging ; random forest; mel-frequency cepstral coeffi-cients MFCC ;

    Abstract : Noise is defined as any undesired sound. Urban noise and its effect on citizens area significant environmental problem, and the increasing level of noise has become a critical problem in some cities. Fortunately, noise pollution can be mitigated by better planning of urban areas or controlled by administrative regulations. READ MORE

  4. 4. Auditory immersion and the believability of a first-person perspective in computer games : Do players have a preference between mono and stereo foley, and is one perceived as more believable?

    University essay from Luleå tekniska universitet/Medier, ljudteknik och teater

    Author : Daniel Wennerberg; [2019]
    Keywords : Audio; Games; Game audio; Computer games; Sound; Sound effects; FPS; FPP; First Person shooter; First Person Perspective; Foley; Stereo Foley; Mono Foley; Mono vs Stereo; Avatar; Self-produced; Immersion; Believability; Preference; Mid-side; Recording technique; Unreal Engine;

    Abstract : Based on previous research on spatial attributes in foley and the concept that auditory immersion in first-person perspective computer games is enhanced by believable sound effects, this study explores if there is a connection between stereo foley and the believability of the first-person perspective, and regardless, if there is a preference to either mono or stereo foley. An interactive listening test was created in unreal engine 4, where 20 subjects, all considered gamers, played three levels that differed visually and in auditory content. READ MORE
