Shock Absorption and Noise Reduction
Seat surface vibration
We attached sensors to seat surfaces to measure the vibration of seat surfaces.
Sound pressure around ears
We measured sound pressure around ears when riding over bumps comparable to gaps of bridge joint.
We found that sound pressure was reduced by 8% when the front passed and 30% when the rear passed. Performance Dampers make the interior of vehicles quieter, which can contribute to improving the quality of the interior space.

*It may not be possible to obtain sufficient benefits, depending on the driving environment, including road surface conditions and vehicle speed.
*Individual differences exist in how benefits are felt.
