In Prison Break SE1E5 "English, Fitz or Percy", Attorneys Veronica Donovan and Nick Savrinn bring a video tape of a murder, in where the suspect is seen on tape shooting another man with a gun in an underground parking lot, to a video expert to analyse the video for any proof it was doctored.
The expert claims that the visual aspects of the tape are spot on but when he inspects the audio track of the tape at the moment the gun is fired, he notices that the gunshot sound "dies" as soon as the gun is fired. He then tells the attorneys:
The problem with your eyes is that they play tricks on you. But your ears don't lie. Here's the audio track from the tape, sound pretty true right? But noise is a lie. See it just doesn't die like that. Stripped down those levels should be dancing. A room that size would give you a blam, blam, blam, blam. You know? Like one off each wall, split second after each other. On yours, the reverbs bouncing at the same time. The sound of the gunshot wasn't recorded in that room."
Is there any truth behind what he says? That if the a gun was fired in a large room that the sound wouldn't just "die" instantly but remain for a while.
