Human Response to Explosion-Induced Noise and Vibrations
Abstract
Performance evaluation of missiles and small ammunition is usually associated with explosions in which detonation is initiated above or below ground within previously approved test ranges. The magnitude of induced vibrations and noise from these sources are usually difficult to identify and are unconsciously registered as disturbing by the human perceptive system. In addition, the induced vibration may cause damage to nearby structures, which can result in expensive law suits. With the growth of population and encroachment of civilian neighborhoods onto military test sites, the requirements to condition and control levels of noise and vibrations become more stringent. Similar situations also arise during construction of tunnels or other infrastructures in which explosives are used for excavation in urban areas. Within the test sites, the peak magnitudes of noise and vibrations that can be tolerated by military personnel are usually much higher than those for civilians in urban areas. This paper provides an insight into assessment of human response to explosion induced noise and vibrations by considering both military and civilian requirements. These requirements are used to develop a method to determine the maximum TNT equivalent weight of explosives that can be detonated at a given site without causing annoyance of civilian population. Also, this paper highlights the importance of the site specific ground conditions on blast-induced vibrations.
