(原创)In cities, the everpresent dull background roar (轰鸣) of planes, cars, machinery and voices is a fact of life. There is no escape from it and I was beginning to be driven mad by it. In an attempt to recapture some peace, I travelled to a temple, a small poor house and a mine 2km underground — all very quiet but not the holy place of silence. The one place I was most excited about visiting was the anechoic (无回声的) hall.
