Project 1 - Part 4

<--Part 3 | Overview

Assume the receiver is a human listening binaurally. The interaural distance in an adult subject is 17 cm. Repeat the
preceding parts for this scenario by ignoring any head shadow effects. Generate the stereo signals appropriate for setups (1) and (2).

Results

Conclusions

It actually sounds like the object is moving past you. The combination of the changing frequency and loudness, as well as the
stereo seperation really fools the mind. There are still artifacts, but the doppler effect is very apparent.
