The formula to convert a dB value to a normal value is:
\[ \text{NV} = \text{RV} \times 10^{\left( \frac{\text{dB}}{10} \right)} \]
Where:
A decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, often power or intensity. Decibels are commonly used in acoustics to quantify sound levels relative to a reference value. The decibel scale is logarithmic, meaning that a change of 10 dB represents a tenfold change in intensity.
Example 1:
Using the formula:
\[ \text{NV} = 1 \times 10^{\left( \frac{20}{10} \right)} = 1 \times 10^2 = 100 \]
Example 2:
Using the formula:
\[ \text{NV} = 2 \times 10^{\left( \frac{30}{10} \right)} = 2 \times 10^3 = 2000 \]
