In this section, we will discuss the results of both the MATLAB simulation and the DSK and the areas that need improving.

Matlab simulation results

In running our simulation, we discovered that while our region output was not always correct, we maintained accuracy within22.5. Tha algorithm seemed to have the most difficultly on the edges of the field of view. Our exact results can befound in and .

Results with the dsk

In testing our DSK algorithm, we started with the ideal signal, generated using Matlab. The results had more errorthan in Matlab, but seemed reasonable at the time. However, in multiple trials of the same ideal signal, the DSK respondeddifferently each time, indicating that our algorithm still needed a bit of work.

When we tried to implement the same algorithm using a real signal, generated from a computer across the room, we receivedvery poor results. In the end, the DSK could tell whether the signal came from the left or the right, but only when the labwas quiet and empty. Also, the program was very sensitive to alternate signal paths and the general acoustics of the room.All in all, our program was not very reliable, as shown in .

Areas of improvement

All in all, we need to start the improvement by doing a better job designing and checking the array beampattern. Also, weneed a better algorithm for integration. For this algorithm, we need to know how much of a cycle is needed, how integrationlength affects accuracy, and how to deal with non-periodic signals. Finally, we need a better understanding and controlover the room acoustics, as well as more time to fully test the algorithm.
