Decibel level after combining sources
Add independent incoherent levels wey you measure on di same basis.
Your numbers
Di combined level
All levels must use the same reference, weighting and observation location. Coherent sources need phase information.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
Use L = 10log₁₀[Σ10^(Lᵢ/10)]. Lᵢ na independent incoherent levels for dB, with di same reference, weighting and location. Di combined level L dey use di same basis.
Add independent incoherent levels wey you measure on di same basis.
Example wey show the calculation
- Levels wey dey independent (dB)
- 60, 60
- Di combined level
- 63.0102999566 dB
Where e fit work and limits
All levels must use the same reference, weighting and observation location. Coherent sources need phase information.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
