Background. 3D sound propagation is important for immersion and realism in interactive and dynamic virtual environments. However, this is difficult to model in a physically accurate manner under real-time constraints. Computer graphics techniques are used in acoustics research to increase performance, yet there is little utilization of the especially efficient rasterization techniques, possibly due to concerns of physical accuracy. Fortunately, psychoacoustics have shown that perceived realism does not equate physical accuracy. This indicates that perceptually realistic and high-performance 3D sound propagation may be achievable with rasterization techniques. Objectives. This thesis investigates whether 3D sound propagation can be modelled with high performance and perceived realism using rasterization-based techniques. Methods. A rasterization-based solution for 3D sound propagation is implemented. Its perceived realism is measured using psychoacoustic evaluations. Its performance is analyzed through computation time measurements with varying sound source and triangle count, and theoretical calculations of memory consumption. The performance and perceived realism of the rasterization-based solution is compared with an existing solution. Results. The rasterization-based solution shows both higher performance and perceived realism than the existing solution. Conclusions. 3D sound propagation can be modelled with high performance and perceived realism using rasterization-based techniques. Thus, rasterized 3D sound propagation may provide efficient, low-cost, perceptually realistic 3D audio for areas where immersion and perceptual realism are important, such as video games, serious games, live entertainment events, architectural design, art production and training simulations. / Bakgrund. 3D-ljudpropagering är viktig för inlevelse och realism i interaktiva och dynamiska virtuella miljöer. Dock är detta svårt att modellera på fysiskt träffsäkert sätt med realtidsbegränsningar. Tekniker inom datorgrafik används inom akustikforskning för att öka prestanda, ändock används knappt de synnerligen effektiva rasteriseringsteknikerna, möjligtvis på grund av osäkerhet kring fysisk träffsäkerhet. Lyckligtvis har psykoakustiken visat att uppfattad realism inte är detsamma som fysisk träffsäkerhet. Detta är en indikation på att högpresterande och perceptuellt realistisk 3D-ljudpropagering kan åstadkommas med rasteriseringstekniker. Syfte. Denna avhandling undersöker huruvida 3D-ljudpropagering kan modelleras med hög prestanda och perceptuell realism med rasteriseringstekniker. Metod. En rasteriseringsbaserad lösning för 3D-ljudpropagering implementeras. Dess perceptuella realism mäts genom psykoakustiska utvärderingar. Dess prestanda analyseras genom körtidsmätningar vid varierande antal ljudkällor och trianglar, och teoretiska uträkningar över minnesanvändning. Den perceptuella realismen och prestandan hos den rasteriseringsbaserade lösningen jämförs med en existerande lösning. Resultat. Den rasteriseringsbaserade lösningen påvisar både högre perceptuell realism och prestanda än den existerande lösningen. Slutsatser. 3D-ljudpropagering kan modelleras med hög prestanda och perceptuell realism med rasteriseringsbaserade tekniker. Alltså kan rasteriserad 3D-ljudpropagering bistå med effektivt, billigt och perceptuellt realistiskt 3D-ljud för områden där inlevelse och perceptuell realism är viktiga, såsom videospel, seriösa spel, live underhållningsevents, arkitekturdesign, konstproduktion och träningssimulationer.

Spectrogram analysis of the most popular works of Adam Young’s four major projects; Owl City, Sky Sailing, Port Blue, and The Score Project. Spectrograms reveal several elements separate to what waveforms can show, and better show elements like frequency saturation, frequency ranges, overtones, and timbral sections. All these elements also can be used to better describe the phenomenon of the Autonomous Sensory Meridian Response (ASMR) and can also be seen on a spectrogram. Because of the ability to see these different elements, a spectrogram provides a good vehicle to analyze and compare elements of Young’s works and ASMR.After analysis, Young’s works show similar types of spectrograms to ASMR content, but the link between the influences between the two is not certain, it is probable that popular music and the ASMR phenomenon are linked in some measurable way. This thesis provides insight into how to further and continue music and ASMR research.

Sustainable urban design requires human wellbeing to be prioritized, considering all human senses (Torigoe, 2002). Sound, which is often overlooked in the municipalities planning offices, affects health in both positive and negative manner. The general approach for handling sounds in cities are through quantitative measurements such as noise abatements and decibel measurements, while the qualitative visual and audial perception; also known as psychoacoustics, is disregarded (Raimbault & Dubois, 2005; Steele et al., 2020; Cerwén, 2016). Research also show that urbanisation decreases pleasant sounds to the human ear(Steele et al., 2020; Beatly, 2012), and some scholars argue that people are losing their skill to identify and name what they are hearing (Schafer, 1994 & Westerkamp, 1974). In this thesis the Western harbour area in Malmö, flagged as exemplary sustainable urban development model, has been using soundscape methodology of soundwalks to contribute to a better understanding of sound perception and the functions of the identified sounds. The Western harbour has previously had troubles getting BREEAM-certifications in the past due to noise(ÅF, 2013), and previous surveys by the Malmö municipality present that the wind is a large unpleasant factor to both residents and visitors’ perception of the area (Kristensson, 2013).The results show similarities to presented studies, for example with birdsong being identified as a pleasant sound whilst traffic being an unpleasant sound. Moreover, most identified sounds by the soundwalk respondents were loud and intense, indicating a lack of listening to less-intense, more quiet sounds. The thesis show that qualitative soundscape methodologies can highlight further dimensions of sound beyond decibel levels, positions sound as a central dimension of sense of place. The thesis provides suggestions for the municipality to have updated information and state what sound actions is being made in each area in the city to include sound and acoustic wellbeing as a central dimension of their sustainable urban development, in order to be able to reach their own goal of having all stakeholders working in the same direction. Along with the fact that the Swedish noise abatement law’s approach is preventative, but does not include the aspect of social change in a space after it is built (Kling, 2013; Malmö comprehensive plan, 2013; Dalman, 2013), since the city of Malmö have grown quickly and is still facing a rapid expansion in demographics (SCB, 2021), as Raimbault & Dubois (2005) argue, denser cities are more noisy.

The purpose of this study was to determine the effects of an auditor's past musical training and experience on the intelligibility of selected vowel sounds at differential pitch levels. The specific problems of the study were to investigate the effects of extensive vocal music training, extensive non-vocal music training, and limited or no music training on an auditor's ability to discriminate accurately selected vowel sounds performed at various pitch levels. The effects of pitch and vowel sound on auditor recognition of vowel sounds in singing and the ability of each singer to be intelligible to auditors was also investigated.
