1. 1. Evaluation of Methods for Sound Source Separation in Audio Recordings Using Machine Learning

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Amanda Gidlöf; [2023]
   Keywords : Sound source separation; signal processing; audio processing; speech enhancement; speaker identification; speech separation; speech processing; speaker separation; single channel; multi channel; cocktail party problem; machine learning; neural network; deep learning; deep neural network; convolutional network; dual-path network; filter-and-sum network; recurrent network; beamforming;

   Abstract : Sound source separation is a popular and active research area, especially with modern machine learning techniques. In this thesis, the focus is on single-channel separation of two speakers into individual streams, and specifically considering the case where two speakers are also accompanied by background noise.

3. 2. Blind Acoustic Feedback Cancellation for an AUV

   University essay from Linköpings universitet/Reglerteknik

   Author : Hampus Frick; [2023]
   Keywords : acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

   Abstract : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. READ MORE

4. 3. Speech Intelligibility in Radio Broadcasts : A Case Study Using Dynamic Range Control and Blind Source Separation

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

   Author : Martin Linder Nilsson; [2022]
   Keywords : Speech enhancement; speech intelligibility; audibility; dynamic range control; blind source separation; object-based audio; public service.;

   Abstract : Creating the optimal balance between dialogue level and ambient sound is extremely important in media productions. This process is however inherently difficult due to that people’s requirements and preferences are not uniform. READ MORE

5. 4. Experimental Study of Installation Effects on Cooling Fan Noise

   University essay from KTH/Marcus Wallenberg Laboratoriet MWL

   Author : Yu-Yu Lu; [2021]
   Keywords : Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

   Abstract : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources.

6. 5. Domain Adaptation for Attention Steering

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Johanna Wilroth; [2020]
   Keywords : Technology and Engineering;

   Abstract : A major problem in the development of intelligent hearing aids is often referred to as the cocktail party problem. It describes the remarkable ability of the human brain of filter out unwanted sounds in a noisy environment, while focusing on a single talker or conversation. READ MORE
