The speedglue sound
The famous Hungarian player Tibor Klampar is credited with the invention of speedgluing. He applied the glue secretly, and it was the special clicking sound his rubbers produced that was noticed by his fellow players during training.
The Tensor sound
Rubbers incorporating Tensor technology not only have a permanently integrated speedglue effect, they also make the same clicking sound as speedglued rubbers. The volume of the clicking is dependent on the magnitude of the integrated speedglue effect and the softness of the sponge. The softer the sponge, the louder the sound.
Ball control
The more accurately a ball is hit, the louder the sound produced by rubbers with an integral speedglue effect. And a ball that has been accurately hit lands exactly where the player wishes it to land. Players therefore subconsciously use the sound as a regulatory mechanism. If the sound is poor and the shot inaccurate, then the player will try to 'catch' the sound again with the next shot. If the sound is right, then the shot will also be a good one. The sound of Tensor is enjoyable and aids ball control.
