Speaker Efficiency Formula
The following formula is used to calculate the Speaker Efficiency.
Es = 10 ^ [(S – 112)/10]
- Where Es is the Speaker Efficiency (%)
- S is the total sensitivity (dB)
How to Calculate Speaker Efficiency?
The following two example problems outline how to calculate the Speaker Efficiency.
Example Problem #1:
- First, determine the total sensitivity (dB). In this example, the total sensitivity (dB) is given as 105.
- Finally, calculate the Speaker Efficiency using the equation above:
Es = 10 ^ [(S – 112)/10]
Inserting the values from above and solving the equation:
Es = 10 ^ [(105 – 112)/10] = .199 (%)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
total sensitivity (dB) = 102
Entering these values yields:
Es = 10 ^ [(102- 112)/10] = .1 (%)
