The sound ranging operators used equipment that augmented human hearing. Using the gun flash, the flash crew would determine a bearing to the gun using a theodolite or transit. The sound detection crew would determine the difference in time between the gun flash and the sound of the gun, which was used to determine the range of the gun.
The sounds may be heard at greater distances in the direction of bullet travel than behind or beside the gun. 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 ...
The audible sound of a gun discharging, also known as the muzzle report or gunfire, may have two sources: the muzzle blast itself, which manifests as a loud and brief "pop" or "bang", and any sonic boom produced by a transonic or supersonic projectile, which manifest as a sharp whip-like crack that persists a bit longer.
Boomerang, a gunfire locator, being used by British forces in Afghanistan Shooting Detector Diagram. A gunfire locator or gunshot detection system is a system that detects and conveys the location of gunfire or other weapon fire using acoustic, vibration, optical, or potentially other types of sensors, as well as a combination of such sensors.
According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.

It is widely accepted within interdisciplinary circles that for a standard rifle firing full-powered cartridges (e.g. .308 Winchester), "long range" means the target is more than 600 m (660 yd) away, [citation needed], while "extreme long range" is generally accepted as when the target distance is more than 1,000 m (1,100 yd) away from the shooter.
Mates may emit low, mooing sounds that sound like a cow. Shoebill families also use high-pitched whines to communicate. Chicks make “hiccup”-like sounds to let their parents know they’re hungry.
