Project #18: Noise source localisation using a rotating microphone

Back

Description:

Sound source localisation using audio signals has been a key research area in signal processing because of its various applications. One of the applications is localising noise sources. Microphone arrays (array of more than one microphones) have been commonly utilised to achieve the purpose, however, reducing the number of microphones employed in the system has been a common interest of practical engineers. The previous year students modified an existing signal processing algorithm and implemented it on a mobile robot equipped with a rotating microphone. The study has proven that the algorithm is able to estimate source angles but its performance was severly degraded when it was implemented on the mobile robot due to various noise in the recording. This year the project will further look into the improvement of the algorithm as well as re-designing the hardware platform of the mobile robot in order to minimise the noise in the recordings.
This project is suitable for students who would like to learn signal processing and some acoustics along with the context of mechatronics.

Type:

Undergraduate

Outcome:

A working signal processing algorithm implemented to a microphone installed on a mobile robot platform.

Prerequisites

This project requires fundamental knowledge in digital signal processing. Students taking this project should have passed MECHENG370 after 2015 otherwise they are expected to enrol in ELECGENG733 as an elective.
