The propagation of noise in a built-up area (on the example of a housing estate in Poznań)

Abstract

The issue of the negative impact of noise on the natural environment is frequently ignored (in spite of its universality), in particular as regards urban and heavily built-up areas. The research presented herein was concerned with a housing estate located in Poznań (Poland). Its area totals approximately 0.55 km 2. The area contains structures covered by acoustic protection (multifamily building development and multi-family residential development). Noise level measurements were performed at designated points. The research made use of the Database of Topographical Structures-a digital study with a level of detail corresponding to a map on a scale of 1:10,000. It served as a backdrop for presenting the location of measurement stations and the sound level distribution; structures subject to protection against noise and areas with unfavourable acoustic conditions were both indicated. The results of the study may prove useful in administrative urban planning undertakings concerned with decreasing the noxiousness of noise or preserving areas characterised by a relative acoustic comfort.

Applications of 3D City Models: State of the Art Review

“…In Europe, the utilisation of 3D city models for this application surged after the implementation of the Environmental noise Directive 2002/49/EC [237] which requires EU countries to produce strategic noise maps in order to inform the public about noise exposure and its effects [238,239]. While 2D GIS is frequently used for this purpose [76], 3D geoinformation provides an advantage over it, as due to refraction, sound levels may considerably variate at different elevations of the same planar coordinates [240].…”

Optimization of Measurement Points Choice in Preparation of Green Areas Acoustic Map

“…While measuring the sound level, it's also important to notice the dynamics of the analyzed areas. Many authors pay attention to this [1,8,9,12]. The park is used differently depending on the time of a day or a year.…”

3 Dimensional data research for property valuation in the context of the LADM Valuation Information Model

“…Estimation of the propagation of noise is another use case that has been used in valuation activities. In noise analysis, 3D data provides an advantage over 2D data due to the refraction of sound level at different elevations (Kubiak and Ławniczak, 2016). There are some studies investigating the relationship between house prices and noise with 2D data.…”
