identical coherent source level sum calculator online
Use identical coherent source level sum online for source level dB, source count. Equal phase at the receiver; independent sources require power addition instead. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.
How to use it
Enter source level dB. Set source count. Select Calculate and check the labeled output. Copy or download the JSON result.
Options and example settings
Calculation method
combined_level_dB = source_level_dB+20*log10(positive(source_count)) (^ means exponentiation; trig functions ending in d use degrees).
Worked examples
Apply identical coherent source level sum to the case below, keeping the displayed units and assumptions. Equal phase at the receiver; independent sources require power addition instead.

}Choose the right tool
Choose timing tools for tempo and samples, tuning tools for frequency ratios, and level tools for amplitude or power. Coherent signal addition differs from independent-source addition; acoustic room estimates assume simplified conditions.
Limitations and common mistakes
- Equal phase at the receiver; independent sources require power addition instead. Ideal mathematical audio model with supplied values. Real speakers, rooms, hearing exposure and converter performance are not measured.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
