Snickometer In Cricket
This technique was created by Alan Plaskett, this helps to make empires to make the right decision, if the batsman is out or not. A very high sensitive microphone is kept near the stumps, and is connected to the oscilloscope that measures the sound waves when the ball touches the bat. Whenever the ball touches the bat the oscilloscope gives a big wave (of sound). When the oscilloscope wave is played with the slow motion shot. The decision gets very easy for the umpire.
