  1. 1. Recording Bass-Cabinet: Microphone Choice and Microphone Placement

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Diana Carmona Velazquez; [2023]
    Nyckelord :audio technology; recording bass; recording; bass; microphone choice; bass-cabinet; microphone placement; rock; ljudteknik; mikrofon val; bas; rock;

    Sammanfattning : Research on microphone choice and placement has been previously made for a variety of instruments, such as drums, vocals, and guitar, to name a few. However, in comparison, very little research has been made on the bass-cabinet. LÄS MER

  3. 2. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Teodor Renman; Charlie Ringström; [2023]
    Nyckelord :Sound analysis; signal processing; event detection; MFCC; real-time; automatic door; embedded programming; stm32; microcontroller; Technology and Engineering;

    Sammanfattning : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. LÄS MER

  4. 3. En jämförelse av ljudlokalisation i horisontalplanet mellan M&RIE och RIE

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Anton Johansson; Erik Linderoth; [2023]
    Nyckelord :sound localization; hearing aids; adults; normal hearing; M RIE; RIE; ljudlokalisation; hörapparat; vuxna; normalhörande; M RIE; RIE;

    Sammanfattning : Bakgrund: Förmågan att kunna lokalisera ljud är en binaural process som försvåras i samband med hörselnedsättning, eftersom tillgången till akustiska ledtrådar begränsas. Hörapparattillverkare strävar efter att främja användarnas tillgång till dessa ledtrådar genom nya innovationer. LÄS MER

  5. 4. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays

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

    Författare :Jesper Brunnström; [2021]
    Nyckelord :Active noise control; Secondary path modelling; Spatial; Adaptive filter; Multichannel; Least mean squares; Aktiv brusreducering; Sekundärvägsmodellering; Spatial; Adaptiv Filtrering; Multikanal; Minsta kvadratmetoden;

    Sammanfattning : In this work we explore online secondary path modelling (SPM) in the context of spatial active noise control (ANC). Specifically, we are interested in the reduction of broadband noise over a three-dimensional region, without restrictions on microphone and loudspeaker array placement. LÄS MER

  7. 5. Mechanical Design Solutions for Wind Resistant Microphone Ports

    Master-uppsats, Lunds universitet/Innovation

    Författare :Hedvig Sannar; Erik Hagman; [2021]
    Nyckelord :Microphone port; wind noise; Robust Design; speech-in-noise testing; noise reduction; mechanical engineering; Technology and Engineering;

    Sammanfattning : This project’s objective was to gather knowledge of ways to mechanically increase speech intelligibility and decrease wind noise through the design of microphone ports. The project focused on ports that would be applied in outdoor intercom products. LÄS MER
