Make Some Noise
In Make Some Noise we study the impact of the built environment on the propagation of aircraft noise and air pollution. Simultaneously, we look at crossovers between measures for noise abatement and their impact on heat stress and energy-consumption. Instead of conflict, we focus on ways to synergize interest that seem juxtaposed at first sight.
Buildings and green walls as noise barriers
Buildings can act as large noise barriers, yielding a noise shielding effect, also for aircraft noise. The extent of shielding depends on the angle at which sound waves hit a building. The angle is location specific, varying with the altitude and horizontal distance between aircraft and location. Sound levels around the buildings are subject to the shape, height and cladding, and distance between facades. Porous materials, like green walls, are examples of noise absorbents, at least in theory. Green walls can also contribute to the removal of fine particulate matter from the atmosphere.
Data collection to improve quality airport areas
The overarching aim of Make Some Noise is to develop a comprehensive toolbox supporting (urban) designers, municipalities, and developers to improve the quality of areas around airports. In this context, quality means less noise, less pollution, climate-adaptive and a lower demand for energy. Thereby, we focus on the impact of urban geometry, façade cladding and the design of outdoor space.
By linking and amending computational models, the ambition is to improve our understanding of the compatibility of single or combined measures in the light of noise, climate, pollution, and energy. However, computer models are fed with ‘real’ data, meaning that data collection in the real world is essential. The data is needed to teach algorithms and serve as benchmark for the output generated by computational models.
“Noise measures can be linked to climate adaptation, with each penny spent paying off twice. Computer models can support the design process to predict where trees and water features are deemed most effective, for both the soundscape and local climate.”
We are currently collaborating with the municipality of Haarlemmermeer and various other regional partners to draw up plans for the field labs. A first project under the umbrella of Make Some Noise is a climate sensing study, in which we collect weather data in low density and rural residential areas. Results from this study will be used to calibrate urban climatic models.
