Using measurements and simple models the low-frequency sound propagation was investigated at a clearing and adjacent forest stand at the meteorological Anchor Station Tharandter Wald near Dresden (Germany). Particular attention was paid to the meteorological influence on the sound immission at one location because the modified meteorological regime in forest areas leads to a changed sound propagation in comparison to the unaffected case. The first results of the investigations demonstrate a significant meteorological influence on sound propagation already at short distances of some 10 m. The main goal of the study is the description of the atmospheric influence on the sound propagation by means of validated and operationally applicable models under several meteorological and vegetation-specific conditions.
