1.What is the purpose of anti-vibration? The main goal of a tennis racquet vibration damper is to reduce the vibration of the racquet string and then reduce or eliminate the "ping" sound you hear when you hit the ball. This sound is a problem of some tennis players who exist, which is why they use vibration cushioning on their racquets. Basically, they want to dull the ping and make the sound more solid and sharp. 2. Vibration stop is suitable for me? The decision of using a vibration material is subjective. It may work for one player, but it may not be for others. Thats why it is all the right thing for you. For example, if you dont like the ping sound we debated before, then perhaps you should consider trying a vibration dampener. The best way to know if it is for you is to try it out and see if you like it.
