Diese Methode erlaubt eine nicht spektrale Berechnung der Bodendämpfung für beliebig geformte Bodenoberflächen unter den folgenden Bedingungen:
Standardmässig (konfigurierbar) werden beim Anwendung der Formel 11 Reflexionen am Boden vom Typ Gras um 2 dBA abgemindert (für Freq. >190Hz). See Einstellungen ISO-9613 (Berechnungsoptionen).
Selected ground-type elements are considered [e.g., no ground attenuation over hard ground]. This is a non-standard improvement of the alternative method; if this improvement is not wished, please, unselect the ground elements when using this method.
| ❑ | Hinweis: When using the alternative method for ground effects, given that SLIP implements a few improvements to this method, if a calculation strictly according to the standard is preferred over one using such improvements, (1) make sure your source is non-spectral; (2) in the settings for this method, select 0 dB for the setting specifying the loss on grass-reflected paths; and (3) ensure your model does not have (selected) elements that explicitly or implicitly describe the ground surface as being non-porous. |
