sound pipe

Imagine your sitting on your front garden admiring the shining sun when your neighbour comes with that annoying car with the buzzing sound and the exhaust pipe blows out this horrible black smoke.

设想一下，你正坐在自家的宅前花园中享受着明媚的阳光，这时，你的邻居开着那辆嘟嘟作响、排气管冒着可怕黑烟的汽车过来了。

The idea was based on the fact that the time taken for a sound wave to travel along a few feet of pipe was of the order of a thousandth of a second.

这个方案的原理是，声波穿过一条几英尺的管道，大约需要千分之一秒的时间。

This might sound like nitpicking, but the calabash pipe and deerstalker cap combo have become synonymous with Sherlock Holmes, or detectives in general though it is entirely inaccurate.

也许这听起来有点吹毛求疵，但是猎鹿帽和葫芦烟斗却已经成为了福尔摩斯，或者是一般侦探的代名词，尽管这一形象并不属实。

A deep sound came out of the pipe organ.

管风琴发出低沉的声音.
