Hey everyone, Could someone help me out with this/walk me through how it's solved? The Beyer M-160 has a sensitivity rated as -52dB (0 dB = 1mW/Pa) and a rated load impedance of 200ohms. The sennheiser MD-421 has a sensitivity given as -54dB re: 1V/µbar. Which of these microphones is the more sensitive, and by how many dB? Thanks!
