Abstract
A ball testing device having a compact housing with a microphone for receiving the sound generated when a ball strikes a surface and generating output signals. An electrical circuit in said housing is configured to receive the output signals and process the signals to determine the time lapse between the first and second and the second and third successive bounces of the ball and provide the ratio of time lapse between the second and third bounces to that of the time lapse between the first and the second bounce to provide the coefficient of restitution of the ball. Said housing including a display for displaying the coefficient of restitution.
