Our project involves experimenting with noise cancelling techniques in order to improve the quality of sound perceived by the human ear. Our aim is to produce an analogue device that can be incorporated into any audio application to improve the fidelity of the desired output at a particular location in a room. To achieve this, it is necessary to eliminate the distorting effects of reverberations, reflections and undesirable channel characteristics by measuring the perceived sound at a point in a room using a microphone, differentiating between the desired signal and the unwanted distortions and implementing a method that will remove the undesirable components. In addition to this, we aim to create a software implementation to investigate node optimisation over several points, leading to noise cancellation within a bounded area.
