Through the use of a microcontroller, any analog signal can be processed. With the use of an LCD-screen, this project aims to use microphones as an input and plot these analog signals as points on this screen. The signals are processed with filters to make these visually interesting, as well as allowing the use of their full range with the microcontroller. The resulting circuit is contained to allow a more coherent function. It performed as intended, with real time updates and separate visualization of high and low frequencies.

Ökad tillgång till teknik som augmented reality (AR) ger museer möjlighet att utforska alternativa interaktioner för utbildning och ökad tillgänglighet. Den här studien utforskar visualisering av miljöljud på museer i syfte att öka ljudmedvetenhet och förbättra museiupplevelsen. Visualiseringendesignen som utforskas i denna studie använder japansk onomatopoeia som basis. Ett proof-of-concept i form av en virtuell museimiljö skapades i virtual reality (VR). Fyra ljudkällor placerades i miljön och visualiserades. Sju deltagare (6 modersmålstalare, 1 med flytande Japanska) utforskade VR-museet och gav feedback genom ett frågeformulär. Resultaten indikerar ett uttryckt stöd för ljudvisualisering i museimiljöer. Vidare föreslår resultaten att visualiseringen bidrar till att underlätta ljudmedvetenhet samt lokalisering av ljud men inte nödvändigtvis ljudförståelse. Vidare är användandet av onomatopoeia lovande men begränsat. / Increased availability of technology such as augmented reality (AR) provides opportunities for museums to explore alternative interactions for education and increased accessibility. This study explores the visualization of environmental sounds in museums to increase sound awareness and enhance the museum experience. The visualization design uses Japanese onomatopoeia as a basis for this purpose. A museum environment was created in virtual reality (VR) as a proof-of-concept. Four sound sources were placed in the environment and visualized. Seven participants (6 natives and 1 high-proficiency speaker) explored the VR museum freely and provided feedback through a questionnaire. Results indicate support for sound visualization in museum environments. Results also suggest that the visualization helps to aid in sound awareness and sound localization but not necessarily sound comprehension and that the use of onomatopoeia is promising but limited.
