Abstract

Prolonged and excessive exposure to noise inside truck cabins can cause long term harm and adverse effects to drivers. To this end, the objective of this study was to monitor noise exposure at the driver's ear level while driving a Malaysian Army (MA) three-tonne truck using the Integrated Kurtosis-based Algorithm for Z-notch Filter (I-kaz™) statistical analysis method. The recorded raw noise exposure data was analysed using I-kaz™ to provide the I-kaz™ coefficient Z8 and I-kaz™ display, which is a 3D graphical representation of the degree of data scattering. It was found that increase of sound pressure level SPL and truck speed result in increase of data scattering in the I-kaz™ display and value of Z8. This study demonstrates that I-kaz™ is a very effective method for noise monitoring as it can detect SPL changes that are very small.
