  1. 1. 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

  3. 2. Development of a demo platform on mobile devices for 2D- and 3D-sound processing

    University essay from Uppsala universitet/Elektricitetslära

    Author : Frans Rosencrantz; [2020]
    Keywords : Spatial Audio; Raspberry PI; Microphone Array; Dirac;

    Abstract : This thesis project aims for the development of a demonstration platform on mobile devices for testing and demonstrating algorithms for 2D and 3D spatial sound reproduction. The demo system consists of four omnidirectional microphones in a square planar array, an Octo sound card (from Audio Injector), a Raspberry Pi 3B+ (R-Pi) single-board computer and an inertial measurement unit (IMU) located in the center of the array.

  4. 3. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Luke Postema; Johan Davidsson; [2019]
    Keywords : Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

    Abstract : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. READ MORE

  5. 4. 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

  6. 5. Improving Spatial Sound Capturing on Mobile Devices Through Fusion of Inertial Measurement Data

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Pouya Ashraf; [2018]
    Keywords : ;

    Abstract : Through the use of sensor arrays it is possible to extract spatial information about signals present in the environment. For instance position, velocity, distance, etc. READ MORE
