Short description

For noise level measurements, in many cases it is important, where the noise is coming from. The aim of this project is to design a device that is able to locate the noise source in both azimuth and elevation. The resolution should be at least 10-20° for the direction and 1/3 octave for the spectrum. The algorithm should be running on an embedded device, therefore computational complexity and power consumption are critical. Size is also an issue and should not exceed a diameter of 20 cm.

Your Tasks

• Review of literature on sound source localization.
• Implementation and comparison of different sound source localization algorithms (e.g. in Matlab, Python or Julia).
• Recording of a small test database.
• Design of a hardware demonstrator.
• Evaluation of the algorithm.

Your Profile/Prerequisites

• Motivation and interest in the topic.
• Solid Background in Signal Processing.
• Experience with either Matlab, Python, Julia, etc.

This project is in cooperation with NTI-Audio AG, Liechtenstein. There is a financial compensation available that is subject to negotiations between the student and the project partner.
