Industrialisation and affluence has led to rising levels of noise pollution in the environment today. With limited space resources, residential buildings and commercial developments are situated closer together. Prolonged exposure to noise can lead to serious physical, mental health problems and possibly create environmental disturbances.
With countries introducing legislation to control noise levels, businesses are exploring ways to keep their noise levels down, by measuring factory noise levels, using special building materials and utilising engineering and technology to reduce equipment noise to acceptable levels.
1. Define noise level / acoustic
2. General overview of sound insulation and sound absorption
3. Purpose of the tests
4. Define the common misunderstanding that affect the acoustic performance and how to increase acoustic quality of a system
5. Other acoustic related tests
• Sound insulation test suite (a pair of reverberation chambers)
• A large reverberation chamber
• A semi-anechoic chamber
• Portable acoustics measurement devices
