Nonetheless, the design process of such elements requires large amount of time and energy from the designer on a trial and error cycle. Aiming to automate part of this dynamic, especially in its early stages, this paper proposes a sizing and performance evaluation model for noise barriers, created through visual programming and generative design. Thus, from a hypothetical scenario – a terrain adjacent to a highway – it was sought to find the points with the greatest possible attenuation after the insertion of a thin and semi-infinite barrier in free field conditions. Performed with an evolutionary solver, the analyses were organized by the barrier height and type of sound source (point or line sources). Attenuation values were calculated separately for each receiver height and frequency octave band (from 63 Hz to 8 kHz). For simplification purposes, material characteristics and weather effects were not considered. The results shown in the graphs correspond to expectations prior to the simulations – the higher the receiver in relation to the barrier, the lower the sound reduction – proving the efficiency of the method used. The best values could be easily selected and the visualization of the solutions made in real time.porAcesso AbertoBarreiras acústicasRuído de tráfegoDesign generativoProgramação visualAlgoritmos evolutivosNoise barriersTraffic noiseGenerative designVisual programmingEvolutionary algorithmsArtigo10.5216/reec.V19i1.76008
