Noise pollution UNESCO Module 18: Noise pollution Noise is any unwanted sound. Noise can increase stress. Very loud noise can damage your hearing, or even make you completely deaf. Read the following statements. Who might say each of these things? • The weaving machines are very old and noisy. We have all learned to lip-read so that we can chat at work. • I have the television set on all day. It keeps me company. • When I was young, I used to walk in the countryside at night. Then, you could experience complete silence. There's nowhere around here like that any more. • The village is quieter since they built the by-pass. And there aren't so many fumes. • I can only do my homework if there is some good music to listen to on the radio. • I can tell when it's lunchtime, because of the terrible noise coming from the .school playground. • The drills we use make lots of noise and vibrations. But without the coal, there would be no electricity to keep our homes lit and our factories working. • All day long, I hear the sewing machine going in my neighbour's flat. Sometimes it's good to know there's someone there, but sometimes it gets too much. • I used to be woken by the birds singing at dawn. But I never hear that now. • Every night, I am woken by people leaving the club and slamming their car doors. Now, list the different sources of noise mentioned. Can you add any more to the list? Which of these sources may be harmful to someone's health? Try to list them from most harmful to least harmful. (The information sheet on Noise pollution may help you.) Page 1
UNESCOModule 1B: Noise pollution Noise pollution Information sheet Sources of noise • industrial machinery • radio and television • construction work The decibel scale • vehicles, trains, aircraft • children playing • household gadgets Each step of 10 dB on the scale represents an increase of 10 times in the loudness. So, for example, 50 dB is 10 times louder than 40 dB. Noise pollution in the home Page2 --__~ ~ __~ _
