Calculating speaker’s sound pressure level (SPL)
To calculate the Sound Pressure Level (SPL) at a given distance from a speaker, based on
its sensitivity rating and input power, you can use the following formula:
SPL
X
= SPL
ref
+ 10 ∙ log
10
(P) – 20 ∙ log
10
(d)
Where:
• SPL
X
= Sound Pressure Level at distance x (in dB SPL)
• SPL
ref
= Speaker sensitivity (usually given as SPL at 1W @ 1 meter)
• P = Input power in watts
• d = Distance from the speaker in meters
Example: With a CL-4P with 87dB sensitivity, driven by a 20W amplifier, the sound pressure
level 3 meters from the speaker will be:
SPL
3m
= 87 + 10 ∙ log
10
(20) – 20 ∙ log
10
(3) = 90.5 dB SPL
