Zusammenfassung
Im September 2007 legte der Vorsitzende des Regionalen Dialogforums Flughafen Frankfurt im Rahmen eines Anti-Lärm-Paktes einen Vorschlag zur Einführung regionaler Fluglärmindizes vor. Mit diesen Fluglärmindizes sollen die Auswirkungen des Fluglärms auf die Region im Umfeld des Flughafens dargestellt werden. Zur Diskussion stehen der Frankfurter Fluglärmindex (FFI) und der Frankfurter Nachtindex (FNI). Im Vordergrund steht der FFI, der die Zahl der durch Fluglärm hoch belästigten Personen über 24 Stunden innerhalb des durch einen Tag-Nacht-Pegel Ldn von 55 dB(A) abgegrenzten Gebiets darstellt. Der FNI ist als Ergänzung zum FFI gedacht. Mit ihm wird die Gesamtzahl aller zusätzlichen fluglärminduzierten Aufwachreaktionen im Nachtzeitraum von 22 bis 6 Uhr erfasst, wobei Gebiete einbezogen werden, innerhalb derer mit mindestens 0,5 zusätzlichen Aufwachreaktionen zu rechnen ist. Im Planfeststellungsbeschluss zum Ausbau des Frankfurter Flughafens werden diese Indizes unter dem Vorbehalt einer wissenschaftlichen Bewertung aufgegriffen. Diese Bewertung wurde von den Autoren des Beitrags durchgeführt und in einem Gutachten im Juli 2008 vorgelegt. Zentrale Ergebnisse des Gutachtens werden im Beitrag aufgegriffen. Hiernach sind regionale Indizes aus wissenschaftlicher Sicht prinzipiell als Instrument zur Beurteilung der Lärmentwicklungen und zur vergleichenden Bewertung aktiver Lärmschutzmaßnahmen geeignet, solange das hierbei angewendete Fluglärmberechnungsverfahren die Änderungen im Flugbetrieb abbilden kann. Die vom RDF vorgeschlagenen Indizes FFI und FNI stellen gute anwendbare Ansätze dar, wobei aus wissenschaftlichen Gesichtspunkten gewisse Modifikationen und Anpassungen angebracht sind.
Within the context of the Anti-Noise-Pact (ANP), the chairperson of "Regionales Dialogforum Flughafen Frankfurt" (RDF), regional forum for the dialogue at Frankfurt Airport, Professor Dr. Wörner, aims to establish a regional aircraft noise index for the description and control of the noise development in the vicinity of Frankfurt Airport. The following two indices are being proposed: Frankfurt Aircraft Noise Index (FFI), and Frankfurt Night Index (FNI). FFI is the primary index. Based on the 24 hours of the day, it describes the number of subjects highly annoyed by aircraft noise in areas within Ldn-contour 55 dB. FNI is meant to supplement FFI. It solely serves to assess nocturnal air traffic by displaying the number of awakenings additionally induced by aircraft noise emitted between 10pm and 6am, including regions where at least 0.5 additionally aircraft noise induced awakenings are expected. In the zoning decision of the Department of Economic Affairs, Transport and Land Development of the state Hesse the concept of noise assessment based on noise effect indices is supported, but only if the proposed indices are subjected to a scientific evaluation. This evaluation was done by the authors of this article. The evaluation report was published in July 2008. Main results of the expertise on the noise effect indices are presented in this article. From a scientific point of view, a regional index is in principle suitable to assess aircraft noise development around the airport. A regional index can also be used as a comparative tool to assess the effects of different active noise control measures as long as the underlying noise calculation method is able to reproduce the acoustical effects of changes in air traffic. The indices FFI and FNI are principally suitable to fulfil these purposes. However, several recommendations are given in order to improve the indices initially proposed by RDF.
