Unlike basic software that assumes an infinite baffle, King's worksheets allow designers to perform detailed "what-if" analyses to understand how specific geometry changes affect sound. They are primarily used for:
King chose Mathcad because of its ability to handle complex and differential equations while displaying them in a readable, "whiteboard" format. This transparency allowed users to see the physics at work, rather than just interacting with a "black box" software program. The worksheets calculate the complex impedance and pressure at both the driver and the terminal (port), then sum them to show the final acoustic output.
