This is a typical slot machine loop-able sound effect that is commonly played during the reel spin.
If you intend to use this sound effect loop for your slot machine game, please consider to pause the sound play each time you stop the reel spin. So that the loop sound can be started from the previous position in the following game play. By doing so it sounds more variated. Besides you can create a flow of game play this way, which would unconsciously drive players to keep on spinning without a pause.
