Abstract
The intensity of the airborne shock wave (AHW) impact on the structures located in the area of blasting operations, when designing blasting operations, is estimated by the value of excess pressure at the front of the wave. As an admissible level of exposure is usually taken the overpressure at the front of the shockwave 700-800 Pa, at which the destruction of glazing of buildings does not occur. However, the dynamic waves formed during the explosion with a pressure drop of about 1 kPa with low (16-60 Hz) and infra-low frequencies can cause dizziness and headaches in the population.
