6. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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

7. Development of a demo platform on mobile devices for 2D- and 3D-sound processing
University essay from Uppsala universitet/ElektricitetsläraAbstract : 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.

8. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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

9. Low Complexity Beamformer structures for application in Hearing Aids
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : 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

10. Real-Time Multiple Audio Beamforming System
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : The Cocktail party problem is a known problem within audiology and relates to a person’s ability to understand and separate speech from a noisy background with multiple speakers. This master’s thesis, in collaboration with Eriksholm Research Center, part of the company Oticon, developed a real-time system to help people with Hearing Impairment (HI) handle this problem by using a microphone array and a Minimum Variance Distortionless Response (MVDR) beamformer.
