DOI 10.1007/s10661-015-4994-4
The original article contained an error.
The (=) symbol in equation 4 was written as (-) in PDF version. However, it has been addressed and is not anymore present in the published copies of the article.
The corrected Equation 4 is shown below.
$$ {L}_{\mathrm{Aeqd}}=10\times \left[\frac{1}{16}{\displaystyle \sum_{i=1}^{16}{10}^{0.1{L}_{\mathrm{Aeqhi}}}}\right]\left[\mathrm{dB}\left(\mathrm{A}\right)\right] $$
