Gunshot

A gunshot is a single

Multiple discharges of one or more firearms are referred to as gunfire. The word can connote either the sound of a gun firing, the projectiles that were fired, or both. For example, the statement "gunfire came from the next street" could either mean the sound of discharge, or it could mean the bullets that were discharged. It is better to be a bit more specific while writing however. "The sound of gunfire" or "we came under gunfire" would be more descriptive and prevent confusion. In the latter phrase, in particular, "fire" is used more (i.e. "under fire"), as both words hold the same general meaning within the proper context.

Gunfire characteristics

There are three primary attributes that characterize gunfire and hence enable the detection and location of gunfire and similar weapon discharges:

1. A muzzle flash which occurs when superheated gases and incompletely combusted propellant residue are secondarily ignited upon contact with fresh ambient oxygen after being expelled out the gun barrel
2. A
   sound pressure level (SPL) of 140 dB or louder.^[1]
3. A
   supersonic
   speeds.

Urban areas typically exhibit diurnal noise patterns where background noise is higher during the daytime and lower at night and the noise floor directly correlates to urban activity (e.g., automobile traffic, airplane traffic, construction, and so on). A firearm's muzzle blast may be masked by ambient noise during the daytime, but may be detected at greater distances during the quieter hours of darkness. A popular urban gunfire locator system typically uses six to ten audio sensors per square mile for trilateration.^{[2][failed verification]} (two or three per square kilometer)
