Zone-based indoor mobile noise monitoring

High noise levels are increasing every day. The rapid development of most world economies has encouraged most countries to move towards industrialization. Some of the sources of noise are indoor appliances within our homes and offices. There are also outdoor sources of noise that cause discomfort examples include traffic, construction sites and factories. This paper looks at the new approaches adopted in the monitoring of noise emission levels. It adopts an approach which involved the use of mobile phones to measure and monitor indoor noise exposure in four vital areas. Mobile phones were used to improve the methods of collecting environmental data.
