The Web of Evil

I remember when the airport first opened they did indeed have those "sound showers" dotted around the place, whose output you could only hear by standing directly under the speaker, and yes, you were enveloped in the relaxing sound of the sea, or a forest, or a baby laughing, or, in one arguably misjudged instance, a baby crying. I haven't been aware of them for a good couple of years now, which means that either they were a temporary installation or their maintenance was judged less of a priority than, say, the travelators.
