PRESS RELEASE: To combat this problem, EMS Brüel & Kjær has announced the addition of a blast overpressure microphone to its Vibration Monitoring Terminal (VMT). The VMT is a versatile solution for monitoring ground vibration; now with the added microphone, it provides a complete blast monitoring solution.

The VMT fully meets the requirements of the International Society of Explosive Engineers, ISEE 2017 for ground vibration and blast overpressure monitoring. It can be used in either a permanent installation or as a portable solution. Units work standalone or as part of a multi-location noise and vibration monitoring network with EMS' Sentinel compliance service.

Using the VMT and blast overpressure microphone can give mine staff and noise and vibration consultants a full record of compliance to optimise operations and to use when responding to complaints.

The company stated that for mining staff and noise and vibration consultants measuring the impact of blasts around mines, the blast overpressure microphone, when used with the VMT, provides a durable and robust solution that, unlike many other industry-standard solutions, continues to meet the ISEE requirements even after being used for an extended time in the field.

Additionally, it can be used in either a permanent installation or as a portable solution. Units work both standalone or as part of a multi-location noise and vibration monitoring network with EMS' Sentinel compliance service.
