How is blasting noise and vibration measured?
A seismograph is used to measure both of these effects of blasting. Seismographs are set up next to the closest structure to the blast site. These machines record the ground vibration and noise generated by the blast. This information is used to determine if the blast has exceeded the limits set in the regulations. What records does the blaster have to keep? The blaster is required to keep detailed records of each blast. These records contain the size, time, and location of the blast, the amount of explosives used, and the results of the seismograph monitoring. Will you bear or feel the blast? Yes, you could, depending how close you are to the blasting site. Humans are fairly sensitive to noise and sound. What you may feel does not necessarily mean that damage is occurring.
