Noise control officers have been visiting Pembrokeshire schools to spread the word about noise. In special lessons on noise children learned what noise is, how it is transmitted, how is it measured, how it can cause problems and what can be done to prevent noise disturbance. The talks were followed by a practical demonstration of noise monitoring equipment and a shouting competition! The school visits were part of Noise Action Week 2007, which is co-ordinated by the National Society for Clean Air (NSCA). Now in its ninth year, it has become an established annual event enabling noise-control officers to highlight their role in trying to improve the quality of life for everyone.  Noise disturbance is becoming an increasing issue in society with more and more noise complaints being received about both commercial and domestic sources. "The most frequently complained-about noise is that from neighbours," said Sarah Johns, senior environmental health officer with the council's public protection.  "Most neighbourhood noise problems are often the result of thoughtless or anti-social behaviour. Proactive education on noise is fundamental in tackling neighbour noise and Noise Action Week gives us an opportunity to promote a responsible attitude towards noise and to raise awareness of its impact," she said. "We are all responsible for the noise we make in our own homes and community and its impact on others."
