This paper describes the ENVIB software system, which has been developed in a menu-driven form to aid in the monitoring and assess- ment of vibration caused by routine blasting operations and for research and development projects. The paper gives an outline of the capabilities of the system by means of screen-dumps and a general descriptive commentary. Technical notes have been added where appropriate to further describe the system._x000D_
The ENVIB system covers: I . Analysis of blast vibration results, and preparation of graphs and tables for control and estimation purposes. 2. Effects of atmospheric conditions and air vibration propagation._x000D_
3. Real-time acquisition and analysis of analogue blast vibration sig- nals directly from transducer equipment or from FM tapes. 4. Analysis of digital files on floppy disc or transferred via the serial port from blast monitoring equipment. 5. Transfer function calculation for structure response studies.
