| Vibration (Frame) |
The lingering, low-frequency oscillation of the racquet after ball contact that players feel. Generally, more flexible racquets produce greater low-level vibration than stiffer frames. Often confused with string vibration, frame vibration has a shorter duration and cannot be reduced using small, rubberized string vibration dampers. Some handle systems and large grommets (Prince's Sweetspot Suspension System, Wilson's Power Holes) are effective at reducing frame vibration. Also, hitting the Node area of the sweetspot produces the least amount of frame vibration. Post-production methods for reducing frame vibration include adding weight and stringing at mid-range. String vibration dampers will not reduce frame vibration.
