Removal of noise from speech.

Title
Removal of noise from speech.
Introduction
Mechanical and Simulation Engineering is a department in Volvo Construction Equipment Wheel Loader organization in Eskilstuna. The group focuses on different areas within simulation and mechanical engineering. We are 16 people in the department and even though we work in different fields we always support and help each other.
The foundation in our work is trust and passion in what we do. The work is usually organized in cross functional projects small or large with other departments across the Volvo world. In such work where every team member is a part of the puzzle teamwork and communication are crucial in the daily project work to create an open and friendly working environment.
Background
The acoustic operator environment is essential for Volvo Construction Equipment machines. Our cabins are known for their low internal noise levels and that operators will experience a productive work shift in this environment. To further refine the environment, we seek solutions for improved communication with the machine and its operator. This communication solution should ideally work regardless of whether the operator or speaker are located on the inside or outside of the cabin or working remotely.
Description
The thesis work targets to develop methods for removing background machine noise from speech where the speaker may be located on the outside of a cabin and the receiver on the inside of the cabin. It involves recordings in machine environments and development of procedures for processing the sound.
Qualifications
The student/students should have a background in Signal Processing or similar, with good MATLAB programming skills.
Thesis Level: Master
Language: English or Swedish
Starting date: Jan 2022
Number of students: 1 or 2
