Short description

Active Noise Cancellation (ANC) is used to cancel unwanted noise by playing back an inverse of the noise signal. This approach works well for small acoustic enclosures, such as head phones or ducts for low frequencies. The aim of this project is build a demonstrator that can show the impact of different adaptive active noise cancellation algorithms. The idea is to use sewage pipes with openings for microphones and loudspeakers.

Your Tasks

• Implementation of modular real-time active noise cancellation on an embedded device.
• Setup of the hardware, out of sewage pipes, with microphones and loudspeakers.
• Evaluation of the algorithm.

Your Profile/Prerequisites

• Motivation and interest in the topic.
• Solid background in (adaptive) signal processing
• Experience with either Matlab, Python or Julia.
