how can you identify the type of gun by the sound it makes ? Like if you had a recording of a gun shot but you Can't see the gun and you can find the bullet.
You can or can't find the bullet? Big difference...btb4198 said:how can you identify the type of gun by the sound it makes ? Like if you had a recording of a gun shot but you Can't see the gun and you can find the bullet.
Sorry I meant in code. So like I want to write a program than an tell the different. Also you can tell the difference between people's voice by find the fundamental frequency right ?anorlunda said:The same way you tell the difference between people's voices, or the difference between a motorcycle a car and a truck's sound.
Did you look around the ShotSpotter website that I linked to?btb4198 said:Sorry I meant in code. So like I want to write a program than an tell the different.
Yeah ! How do in code that ? What algorithms are they using ?berkeman said:Did you look around the ShotSpotter website that I linked to?
I"m sure their code is proprietary, especially the physical location determination part. Did you see if they claim that they can also distinguish rifle/pistol and maybe the approximate caliber?btb4198 said:Yeah ! How do in code that ? What algorithms are they using ?
They primarily use time-of-flight to multiple sound detectors, but they also have to do initial testing and calibration of an installation to learn about the echo characteristics and multi-path characteristics. Most of the ShotSpotter installation are in towns and city environments, where there are multiple bounces for most of the acoustic paths.btb4198 said:wow how do they know where the gun fire is coming from ? This is what I wanted to code...
Unlike counter-sniper sensors which can only measure a limited range of sounds—the supersonic signature of a sniper’s round with a known ballistic coefficient—SST’s wide area protection system measures the full range of impulsive sounds (sounds which are explosive in nature) found in urban weaponry, from sub and supersonic impulses to explosions.
Being able to identify the type of gun by its sound can provide critical information in forensic investigations and criminal investigations. It can also help law enforcement officers and military personnel determine the type of threat they are facing and respond accordingly.
The type of gun, the caliber, the ammunition used, the barrel length, the environmental conditions, and the distance from the source of the sound can all impact the sound of a gun. Additionally, the presence of silencers, muzzle brakes, and suppressors can also alter the sound of a gun.
The most common methods include acoustic analysis, spectrogram analysis, and waveform analysis. These methods involve analyzing the sound waves produced by the gun and comparing them to a database of known gun sounds.
Yes, there are various devices and techniques that can be used to alter or disguise the sound of a gun. This can make it more difficult to identify the type of gun by sound, but trained professionals with specialized equipment may still be able to make an accurate determination.
Yes, there are limitations to this method, as the sound of a gun can be affected by various factors and can be altered or disguised. Additionally, the accuracy of identification may depend on the quality of the recording and the expertise of the person analyzing the sound. It is also important to note that identifying the type of gun by sound should not be the sole basis for any legal actions or decisions.
