Madhvacarya has no commentary so we present Baladeva Vidyabhusanas. Bhishma become elated hearing the praises given him by Duryodhana. Thus to eliminate the fear he knew Duryodhana was concealing in his heart he roared like a lion, simha-nadam means roaring like a lion and then blew a thunderous blast on his conchshell. By only sounding a blast on his conch shell without speaking Bhishma signified that true to ksatriya or warrior code of warfare he would fight until death.
