Sensitivity (dB) = 112 + 10*Log10(Efficiency)


The Sensitivity of a speaker is a measure of how well it converts input power to acoustic output. Manufacturers will typically provide this number in their data sheets.

The reference for this measurement is 1 Watt injected by an amplifier. The sensitivity is the sound pressure level measured at a distance of 1 meter away from the speaker using a noise meter.

Unit for SPL is dB (1W/1m).

Example Calculation

For a speaker efficiency of 0.5%, the sensitivity is approximately 89 dB.
