  1. 1. Evaluation of ambisonic microphone techniques in conjunction with spot-microphones for 360-degree video within an acoustic environment

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Linus Sjöholm; [2023]
    Keywords : ambisonics; media; microphone; microphone technique; 360-degree video; audiovisual;

    Abstract : In recent years, the popularity of 360-degree video paired with 1st order ambisonic audio has seen a rise on different social media platforms online. Due to this increase in popularity, many new ambisonic microphones have been developed and are now available on the market. READ MORE

  3. 2. Removal of Noise from Speech - A case study of a construction machine

    University essay from KTH/Teknisk akustik

    Author : Tomoya Otsuka; [2022]
    Keywords : signal processing; thesis; beamforming; noise; speech; construction machine; filter; real-time; microphone; measurements; signalbehandling; avhandling; beamforming; buller; tal; byggmaskin; filter; realtid; mikrofon; mätningar;

    Abstract : This report proposes a solution to allow speech to enter a construction machine cabin while removing noise sources. Examples of noises sources include, engine noise, traffic or other construction activities. Survey of the possible methods to remove noise from speech was conducted, however, beamforming was the technique chosen. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

  5. 4. Implementation and Evaluation of Encoder Tools for Multi-Channel Audio

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Tomas Malmelöv; [2019]
    Keywords : Scene based audio; 3D audio; Spatial audio; Ambisonics; HOA; Multi-channel audio; Audio compression; MPEG-H;

    Abstract : The increasing interest for immersive experiences in areas such as augmented and virtual reality makes high quality 3D sound more important than ever before. A technique for capturing and rendering 3D audio which has received more attention during the last twenty years are Higher Order Ambisonics (HOA). READ MORE

  6. 5. Low Complexity Beamformer structures for application in Hearing Aids

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Eleni Koutrouli; [2018]
    Keywords : hearing aids; beamformers; MVDR algorithm; microphone arrays;

    Abstract : Background noise is particularly damaging to speech intelligibility for people with hearing loss. The problem of reducing noise in hearing aids is one of great importance and great difficulty. Over the years, many solutions and different algorithms have been implemented in order to provide the optimal solution to the problem. READ MORE
