This tool calculates the Speaker Sensitivity expressed in dB (deciBels).
Enter the Speaker Efficiency (%) below
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).
For a speaker efficiency of 0.5%, the sensitivity is approximately 89 dB.
- Sound Pressure Level – use the speaker’s sensitivity to find the SPL at a specified distance away from it
- Max SPL of a speaker
- Match an Amplifier with your Speaker – use this to find the required amplification to achieve a desired level of audio performance
- Speaker Dispersion – Find the vertical and horizontal spread at a specified distance away from the speaker.
