The effect of the angle upper edge in shaped noise barriers with a T-shaped upper edge
Background and Objective: Efforts to improve the effectiveness of noise barriers have been made, including shape, aesthetics, form and gender. Therefore, the aim of this study was to investigate the effect of the angle upper edge in shaped noise barriers with a T-shaped upper edge. Materials and Methods: A 2D boundary element method (BEM) was used to predict the insertion loss of the tested ba...
متن کاملPrediction of Jet Noise Shielding
This study is motivated by the development of aircraft that use jet noise shielding by the airframe. Current methods to predict shielding from aircraft surfaces rely on formulae developed for diffraction of sound from omnidirectional point sources. However, the jet noise source is distributed and directional, thus requiring a different approach. In this study, the jet noise source is modeled as...
متن کاملNumerical evaluation of tree canopy shape near noise barriers to improve downwind shielding.
The screen-induced refraction of sound by wind results in a reduced noise shielding for downwind receivers. Placing a row of trees behind a highway noise barrier modifies the wind field, and this was proven to be an important curing measure in previous studies. In this paper, the wind field modification by the canopy of trees near noise barriers is numerically predicted by using common quantita...
متن کاملActive Shielding and Control of Environmental Noise
We present a mathematical framework for the active control of time-harmonic acoustic disturbances. Unlike many existing methodologies, our approach provides for the exact volumetric cancellation of unwanted noise in a given predetermined region of space while leaving unaltered those components of the total acoustic field that are deemed as friendly. Our key finding is that for eliminating the u...
