Vibration induced by powertrain, ancillaries and road can dramatically affect how passengers judge the quality of the ride.
ISO is the brueo often used standard for this purpose. While the on-road subjective assessment provides more realistic ratings of seat vibration quality, it is not cost-effective and does not provide the subjects with the possibility of back-to-back comparisons, that is, comparing two or more different seats, one after another, within the same experimental session.
The relevant studies and standards are based only on the estimation of vibration energy with a frequency weighting function applied and often do not mexsuring into account the amount of temporal variation.
