Microphone Sensitivity Calculator

Convert microphone sensitivity between dBV and mV/Pa and calculate output levels.

Sensitivity (dBV/Pa)

Sound Pressure Level (dB SPL)

Preamp Gain (dB)

Microphone Type

Formula

mV/Pa = 10^(dBV/20) x 1000; Output = Sensitivity x SPL Pressure x Preamp Gain

What is microphone sensitivity?

Sensitivity measures how much electrical output a microphone produces for a given sound pressure, usually measured in dBV/Pa.

Is higher or lower sensitivity better?

Neither is inherently better. Higher sensitivity mics need less gain but may clip on loud sources. Lower sensitivity mics handle louder sounds.

What sensitivity do I need for vocals?

For vocals, a large diaphragm condenser with around -30 to -40 dBV sensitivity is ideal for most recording situations.
