Level Calculations


Level Reduction with Distance

(feet or meters)
Distance 1 from
the sound source
 Distance 2 from
the sound source
 Result: Level drop
at position 2

Calculate max. SPL from a given Sensitivity (1W/1m)

Sensitivity of the Speaker
1W/1m (in dB):
maximal Power Rating
(in Watts):


Result
maximal SPL possible:
