Definition
Hindrance of population by noise generated through urban transport.
Parameter
Percentage of population hindered by urban transport noise, based on hindrance factors for noise exposure data of population by noise bands.
NI = Noise hindrance index [% of population]
i = Average noise Lden of noise band [#]
Pim = Population exposed to noise band i for mode m (road, rail, airplane) [#]
Wim = High Annoyance weight factor for mode m and noise band i [%]
HFLDeni = Hindrance factor at average Ldeni of the related noise band i
LDen= Average sound pressure level over all days, evenings and nights in a year (in this compound indicator the evening value gets a penalty of 5 dB and the night value of 10 dB).

Number of people exposed to different noise bands related to major roads | The input data required to estimate the indicator is related to population exposed to noise by band for each transport mode (road, rail, aviation). Data is available for about 500 urban agglomerations on the EEA website, END's noise map data: the most recent link is: https://www.eea.europa.eu/data-and-maps/data/data-on-noise-exposure-6 | M |

* The column “Costs” provides a qualitative assessment of the budget (staff costs, time, costs for data acquisition, etc.) needed by a city/ urban area for gathering new quantitative data in absence of already available values. For each parameter, the assessment takes into account both the administrative costs and the costs related to searching, acquisition and processing of the needed data; these can be high (“H”), medium (“M”) or low (“L”), or a combination of a pair of them.
