Improving Data Quality for Shallow Seismic Refraction Survey in Noisy Environment

The data used in this research was acquired in an urban area, Damansara, and is highly contaminated by noise due to the location and this made it hard to identify the first break signal. The objectives of this research are to design the field acquisition parameter for noisy area, to formulate new approach for noise reduction using MatLab software, to image the granite interface in the noisy environment and to investigate the possible correlation between Standard Penetration Test (SPT) values obtain from borehole data and velocity values obtain from seismic survey.
