Abstract
Een pilotstudie is uitgevoerd naar de mogelijkheid om
het aantal geluidgehinderde personen te schatten aan de hand van
geluidbelastingskaarten. Als rekenvoorbeeld is de mate van hinder door
geluid van treinverkeer in Nederland bepaald. Blootstelling-responsrelaties
uit de literatuur zijn toegepast op geluidsbelastingsgegevens uit het
akoestisch spoorboekje van de Nederlandse Spoorwegen. Per 500 x 500 m
gebied is het aantal (ernstig) gehinderden door geluid van railverkeer
berekend. Deze aantallen zijn geaggregeerd naar hinderpercentages per
gemeente, per provincie en voor geheel Nederland. Vervolgens zijn de
berekende provinciale en landelijke hinderpercentages vergeleken met de
uitkomsten van de TNO-hinderenquete en de CBS-DLO-enquete. Het blijkt dat
de berekende percentages (ernstig) gehinderden door geluid van treinverkeer
wat lager of in dezelfde orde van grootte liggen als de hindergegevens uit
de TNO-enquete. De grootste meerwaarde van deze modelmatige
hinderberekeningen is de mogelijkheid op scenario�s door te rekenen, zodat
het effect van bepaalde maatregelen en ontwikkelingen op de mate van hinder
geschat kan worden. Daarnaast is de rekenmethode goedkoop en biedt het een
uniforme manier voor verschillende overheden (provincies en gemeenten) om
hinderpercentages te bepalen en onderling te vergelijken. Een periodieke
validatie van de berekende hinder, door middel van een hinderenquete, blijft
uiteraard noodzakelijk.
In this pilot study an estimation has been made of the number of persons annoyed due to exposure to noise. As an example the extent of annoyance caused by noise of railway traffic in the Netherlands has been determined. Exposure-response relationships were derived from the literature and applied to data (model calculations) on noise levels near railways. The number of people (seriously) annoyed by train noise has been calculated per 500 x 500 m area. The results have been aggregated to percentages of people annoyed per municipality, county and for the Netherlands as a whole. Finally the estimated percentages of people potentially annoyed have been compared with data obtained from two national questionnaires which included questions concerning the degree of annoyance due to sound of railway traffic. Although the estimated number of people annoyed were somewhat lower than the percentages from questionnaire data, the percentages were in the same order of magnitude. The major advantage of this procedure is the possibility to make scenario calculations, predicting the effect of for instance (future) noise reduction measures. Furthermore, this method offers a cheap and uniform way to local, regional and national authorities to estimate and compare percentages of people annoyed. However, a periodic validation of the calculations by means of questionnaires and updating the used exposure-response relationships remains necessary.
