Analyzing the impact of aircraft noise on urban areas requires specific consideration of sound propagation over long distances, which is not typically covered by tools designed for indoor acoustics. Although it is unclear to what extent existing parametric tools that combine 3D modeling and acoustic simulation can accurately replicate these spatial scales, they provide a valuable means of exploring design options and optimizing performance. One such tool, Pachyderm, a numerical model based on geometrical acoustics, was used to simulate a field lab near Schiphol Airport to assess its applicability for urban acoustics simulation. The simulation results were compared to in-situ measurements, with a focus on differentiating the effect of air noise attenuation based on varying building shapes and the accuracy of the resulting sound pressure level values. The most decisive factors in reducing noise in the courtyard were found to be the building’s orientation and slope relative to the sound source. However, as the design complexity increased with the addition of features such as shielding, the accuracy of the simulation results decreased.

OtherFollowing the successful BS2021 in Bruges, Shanghai will take the relay in hosting the next worldwide Building Simulation Conference! BS2023 will see the return of the conference to China after 16 years. The regional affiliate, IBPSA-China, is honored to present an efficient, interactive, warm and safe reunion to the community. Please subscribe to our mail list to stay informed.

BS2023 continues to be a Hybrid event. However, with all travel restrictions to China lifted, we highly recommend you to attend in person, for a better social networking experience and a great chance to explore the mainland China.
