  1. 1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Máté Károly Tóth; [2023]
    Nyckelord :Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

    Sammanfattning : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

  3. 2. Phainesthai : Auditory Processes as Tools for Musical Composition

    Master-uppsats, Kungl. Musikhögskolan/Institutionen för komposition, dirigering och musikteori

    Författare :Luka Aron; [2023]
    Nyckelord :music; psychoacoustics; auditory distortion products; tuning; just intonation; phenomenology;

    Sammanfattning : The human auditory system can become an active agent in the production of sound when stimulated with specific tone combinations. The resulting auditory distortion products can be amplified and drawn attention to by employing certain just intonation practices – a compositional technique that may serve as a powerful catalyst for reaching different states of mind in listeners.

  4. 3. Design of auxiliary communication for audio between computers and DSPs : Programming and optimization of computational resources

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Eriksson Janze Oscar; [2023]
    Nyckelord :DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

    Sammanfattning : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. LÄS MER

  5. 4. Automatic Maximum Sound Pressure Level (SPL) Measurements Inside Cars

    Master-uppsats, KTH/Teknisk akustik

    Författare :Luyao Dong; [2023]
    Nyckelord :Audio Measurement; Distortions; Maximum Sound Pressure Level SPL ; Automotive Audio; Ljudmätning; distorsion; maximal ljudtrycksnivå; billjud;

    Sammanfattning : With a growing interest in technical specifications among consumers, there is a need for accessible measurement tools that enable individuals to evaluate the performance of their equipment, including common speakers and car audio systems, beyond what the manufacturer provides. However, the existing measurement systems are often geared towards professionals. LÄS MER

  7. 5. Utvärdering av laddningssystem för elfordon

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Johannes Banous; [2023]
    Nyckelord :Elfordon; laddning; mätningar;

    Sammanfattning : Elfordon är en viktig del av omställningen till en mer hållbar transportsektor och för att kunna nå de uppsatta klimatmålen, både globalt och nationellt. Biltillverkare arbetar ständigt med att utveckla olika komponenter för att kunna optimera egenskaperna, däribland laddning. LÄS MER
