许多作者认为，道路对动物的负面影响主要是由于交通噪音。虽然具有启发性，但过去大多数关于道路噪音对野生动物影响的研究都是在存在道路的其他混杂影响的情况下进行的，例如视觉干扰，碰撞和化学污染等。我们目前，据我们所知，第一次研究，实验性地将交通噪音应用到一个无路区的景观尺度，从而避免了其他混淆方面的道路目前在过去的研究。我们复制的声音的道路上的间隔交替4天的噪音与4天的休息，在秋季迁徙期间使用0.5公里的扬声器阵列内建立的中途停留地点在南部爱达荷州。我们每天都沿着我们的“幻影之路”和附近的一个控制点进行鸟类调查。我们记录了超过四分之一的鸟类丰度下降，几乎完全避免了一些物种之间的噪音和噪音关闭期间沿着幻影道路，并没有这样的影响，在控制网站，这表明交通噪音是一个主要的驱动程序的影响，道路上的动物种群。
Many authors have suggested that the negative effects of roads on animals are largely owing to traffic noise. Although suggestive, most past studies of the effects of road noise on wildlife were conducted in the presence of the other confounding effects of roads, such as visual disturbance, collisions and chemical pollution among others. We present, to our knowledge, the first study to experimentally apply traffic noise to a roadless area at a landscape scale-thus avoiding the other confounding aspects of roads present in past studies. We replicated the sound of a roadway at intervals-alternating 4 days of noise on with 4 days off-during the autumn migratory period using a 0.5 km array of speakers within an established stopover site in southern Idaho. We conducted daily bird surveys along our 'Phantom Road' and in a nearby control site. We document over a one-quarter decline in bird abundance and almost complete avoidance by some species between noise-on and noise-off periods along the phantom road and no such effects at control sites-suggesting that traffic noise is a major driver of effects of roads on populations of animals.
