I placed a camera about 30 feet to the side of some water jug targets at 150 yards and shot at them with unsuppressed and suppressed .223 and .22lr. This allows you to hear the difference in time when various components of the sound of a gunshot arrive at the target. The 3,000 fps muzzle velocity of the .223 is nearly three times the speed of sound so you hear a ballistic crack and the sound of the bullet impact roughly simultaneously, then you hear the sound of the shot a moment later. When the silencer is attached, you can still hear the sound of the shot, just barely, but it is very difficult to detect. The reverse is true for the .22lr. Although the bullet starts out with a muzzle velocity just below the speed of sound, it slows down quite a bit on the way, arriving at about 850 fps. The speed of sound is about 1,100 fps at sea level. This means that the sound of the shot precedes the bullet at the target by a fraction of a second. You hear the shot, then the bullet passing through the air, then the impact. With the silencer attached, you still hear the shot, but very faintly.
