 | | Noise is an increasingly omnipresent, yet underestimated, form of pollution. |
 | | Long periods of exposure to relatively low levels of noise can have adverse effects on human health, such as raised blood pressure, hypertension, disrupted sleep and cognitive development in children (Kiernan, 1997b), diminished working memory span, and psychiatric disorders (Bond, 1996). |
 | | In Amsterdam, 29% of the city's inhabitants complain of noisy neighbours, 28% are regularly disturbed by the jarring sounds of traffic, and 26% suffer the dissonance that comes from living under the airport flight paths. |
