The expression for the DIN A weighting of the noise voltage is:
\begin{equation} DIN_{A}=\frac{2355.0 f^{4}}{\left(1.837 \cdot 10^{-6} f^{2} + 1\right)^{0.5} \left(8.621 \cdot 10^{-5} f^{2} + 1\right)^{0.5} \left(f^{2} + 424.4\right) \left(f^{2} + 1.487 \cdot 10^{8}\right)} \end{equation}The frequency plot is shown below.
