Martin J. King’s Mathcad worksheets are a legendary, free (donation-ware) suite of simulation tools for : transmission lines (TLs), tapered lines, mass-loaded TLs (ML-TL), horn-loaded lines, and open-baffle designs. Unlike simplified box-modeling software (e.g., WinISD), MJK solves 1D acoustic wave equations inside a line with damping material, making it the gold standard for DIY TL design. martin j king mathcad worksheets

, such as transmission lines and horns. Unlike simpler software, these worksheets use a rigorous calculation algorithm based on closed-form solutions of the wave equation to accurately predict complex acoustic behaviors.
