Theory & Logic
Theoretical Background
Physics describes the fundamental mechanism of the universe. The Sound Intensity Level is an essential tool for understanding Sound Intensity Level in quantitative terms. Calculate dB = 10 * log10(I/I0).
Mathematical Formulation
The relationship between the variables is governed by the following equation:
Variable Legend
| Symbol | Parameter | Unit |
|---|---|---|
| i | Intensity (I) | W/m² |
Practical Calculation Example
Problem
Calculating the result when:
- Intensity (I) = 55 W/m²
Solution
Substituting into Eq 1.1:
Result = 10 × Math.log10(55 ÷ 1e-12)
