Sensitivity vs Distance Calculator

Calculate SPL at any distance based on speaker sensitivity and amplifier power. Understand sound drop-off over distance for accurate audio planning.

Calculated SPL at Distance

SPL at 1 meter(s): 88 dB

Example Calculations

Sensitivity (dB) Power (W) Distance (m) Calculated SPL (dB)
88 50 2 91
90 100 5 102
92 200 10 110

Frequently Asked Questions

Sound spreads in all directions, so intensity reduces logarithmically.

Approximately 6 dB for free-field conditions.

Yes, but each speaker’s contribution should be calculated individually or summed correctly.

Yes, reflections and absorption can increase or decrease perceived SPL.

This tool predicts loudness, but damage depends on power handling and clipping.
