Microphone sensitivity help

[ericstrip]

Hey everyone,
can anyone help me solve this/walk me through it?

The Beyer model M-160 has a sensitivity rated as:
-52dB (0dB = 1mW/Pa)
and a rated load impedance of 200ohms.

The Sennheiser MD-421 has a rated sensitivty given as:
-54dB re: 1 V/µbar

Which of these microphones is the more sensitive, and by how many dB?

If you can help, i'd really appreciate it...thank you!
