teddysaur 0 Report post Posted July 23, 2006 Is there a way to calculate the earphone output db? I'm trying to calculate the output(db) out from my earphone. My earphone sensitive is 119db/mW with 27ohm impedence and my player can output 30mw + 30mw at 16ohm. What is the formula? Share this post Link to post Share on other sites
