The Government of Canada has directed the Department of National Defence to encourage our NATO allies to increase use of their facilities at Goose Bay, Labrador. This has already resulted in a substantial increase in the amount of military flying in the area, and more is projected. Much of the flying is done at very low altitude. The aboriginal people in the region (the Innu and, to a lesser extent, the Inuit) are demanding a halt to low-level military flying, and their representatives claim that the noise from the low-flying jet aircraft can cause hearing loss and ear disease. A survey on the ground in the area measured noise levels up to 127.7 dBA with very brief exposure levels. A task force commission to look at the problem concluded that occasionally low-level subsonic overflights might produce noise levels that were potentially damaging to hearing, but that the probability of this happening is at present very low because of the low frequency of flights. This might change if the frequency of flights increases.
加拿大政府已指示国防部鼓励北约盟友更多地使用其位于拉布拉多鹅湾的设施。这已导致该地区军事飞行量大幅增加,预计还会更多。大部分飞行是在非常低的高度进行的。该地区的原住民(因努伊特人以及程度稍轻的因纽特人)要求停止低空军事飞行,他们的代表声称低空喷气式飞机产生的噪音会导致听力丧失和耳部疾病。该地区地面调查测量到的噪音水平高达127.7分贝,且暴露时间非常短。一个专门调查该问题的特别工作组得出结论,偶尔的低空亚音速飞越可能会产生对听力有潜在损害的噪音水平,但由于飞行频率较低,目前这种情况发生的可能性非常低。如果飞行频率增加,这种情况可能会改变。
