Calculation method
Calculation method
Energy-equivalent sound level (dB)
Leq=10log10(sum(t 10^(L/10))/sum t), stabilized by largest level.
Total duration (minutes)
Leq=10log10(sum(t 10^(L/10))/sum t), stabilized by largest level.
Symbols and units
- a
- Sound levels (dB)
- b
- Exposure durations (minutes)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions & limits
Assumptions & limits
- Energy average only; no occupational dose or legal compliance classification. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Energy average only; no occupational dose or legal compliance classification.
