Technique Comparison

It is proposed that low frequency noise/vibration problems are best tackled by a combination of acoustic and microseismic methods, rather than using each method in isolation. A new integrated method was devised and it was demonstrated that ‘the whole is greater than the sum of the parts’. The benefits and versatility of the new method are illustrated with reference to a case study. Unmanned monitoring took place at several houses near to an industrial site, using a multi-channel recording technique. Comparison of various components of the sound and vibration fields in each house was then carried out, which allowed various propagation paths to be distinguished. A range of further signal processing analyses was also employed to aid source determination.
