In recent years, blasting work is being performed near residential dense areas in urban areas, and blasting noise generated here is one of important disasters along with blasting vibration.

Noise from blasting works can be divided into noise from drilling work, noise from blasting wind pressure caused by explosive explosion, and noise from heavy equipment carrying crushed rock. The storm noise (noise) from the space is so large that it causes considerable discomfort and complaints to the neighbors.

In general, blast noise refers to a wave having a frequency in the audible region heard by a human ear among waves propagated with air as a medium. However, even low-frequency vibrations, which are not audible, cannot be heard in the human ear, but they are more dangerous than vibrations in the audible region because the building vibrates to generate secondary noise or cause cracking. The noise in the audible region and the low frequency waves are called "blasting wind pressure" because the noise appears in the form of overpressure in the air.
