随着科技的进步，飞行汽车产生的噪音将比今天的直升机小得多。例如，我们将会采用电子推进系统，而非驱动螺旋桨产生大量噪音的引擎，我们会使用更加安静的电子发动机，用来驱动体积和噪音都更小的旋翼。Uber 的一项研究预测人们感受到的噪音将和今天的电子汽车那样小。
English version
As technology advances, the noise generated by flying cars will be much smaller than today's helicopters. For example, we will use an electronic propulsion system instead of an engine that drives the propeller to generate a lot of noise. We will use a quieter electronic engine to drive the rotor with smaller volume and noise. A Uber study predicts that people will feel the same noise as today's electronic cars.
