Purpose: This study aims to prevent disasters such as structural damage and collapse caused by blasting and impact noise by addressing overall problems related to vibration velocity measuring devices, measurement standards (measurement methods), and the conversion formula between vibration level and vibration velocity during blasting operations. Method: The study involved comparative analysis of measurements taken at construction sites, examination of current laws and institutional systems, and verification of conversion formulas between vibration level and vibration velocity. Based on this, problems were identified and corresponding improvements were proposed. Result: There are currently no statutory regulatory standards for vibration velocity, nor formal approval (type approval) for manufacturing or importing vibration measuring devices, or established measurement standards. Significant discrepancies were observed in the measurement results obtained from five different domestic and international measuring devices. Furthermore, substantial differences were found among the various conversion formulas, which leads to major problems when these measurements are used for blasting design or dispute resolution. Accordingly, improvement measures were proposed to address these issues. Conclusion: It is expected that establishing government-level regulatory standards for vibration velocity, implementing type approval and accuracy tests for vibration measuring devices, enacting legal measurement standards for vibration velocity, and standardizing the conversion formula between vibration level and vibration velocity will help resolve disputes and prevent disasters such as damage to buildings or structural collapse.
