stentorian

The Greek herald Stentor was known for having a voice that came through loud and clear. In fact, in the Iliad, Homer described Stentor as a man whose voice was as loud as that of fifty men together. Stentor's powerful voice made him a natural choice for delivering announcements and proclamations to the assembled Greek army during the Trojan War, and it also made his name a byword for any person with a loud, strong voice. Both the noun stentor and the related adjective stentorian pay homage to the big-voiced warrior, and both have been making noise in English since the early 17th century.
