Abstract
Following the procedure indicated in part I, a canonical solution of the matrix Riemann-Hilbert problem for sound propagation in a gas occupying a half space is presented. The closed form solution is computed numerically for three particular values of the sound frequency. The results compare favorably with a previously known numerical solution.
Sommario
Seguendo il procedimento indicate nella prima parte, si presenta una soluzione canonica del problema matriciale di Riemann-Hilbert per la propagazione del suono in un gas che occupa un semispazio. La soluzione viene poi calcolata numericamente per tre valori particolari della frequenza. I risultati sono in buon accordo con una precedente soluzione numerica.
