OT but I think better than another boring air travel bad spiel - Dyson did some cool computer modelling around Helmholtz acoustic cavities to create quieter fans. I think there's a lot of interesting stuff we can re-visit today because of improved computer power around noise pollution - “At Dyson we make hundreds of incremental changes rather than one leap forward at a time,” said Schneider. “That means we produce and test hundreds of prototypes for each project. 640 prototypes from handmade models to 3D printed designs were made during the development of the Cool fan.” https://www.theguardian.com/technology/2014/mar/06/dyson-silent-fan https://www.theguardian.com/technology/2014/mar/06/dyson-sil...
