What can individuals, people like me and the listeners at home, do to help reduce noise pollution? We can all help by being more considerate and thinking of our neighbours. We can turn down our TVs and stereos early in the morning and late at night. We can choose mobile phone ring tones that are not too loud and disturbing. If we know we're going to make a noise at home, for example if we're having a party, we can warn our neighbours in advance and apologise for the inconvenience. Well, that's all we have time for this evening. Professor Wang, thank you very much for speaking with us. Good night listeners, tune in tomorrow for more on Your World.
