The Seat Effective Amplitude Transmissibility (SEAT) value is the ratio of the vibration experienced on top of the seat and the vibration that one would be exposed to when sitting directly on the vibrating floor. SEAT values have been widely used to determine the vibration isolation efficiency of a seat.
In this study, the subjective evaluations of six persons were compared to the SEAT values estimated from experimentally obtained transmissibility curves for 2 different automobile seats. A vertical gaussian random stimulus was used as input for the SEAT calculations. The SEAT values were estimated using the power spectral density of the vertical vibration input at the seat track and the measured transmissibility data to compute the response in the vertical direction and horizontal direction at the seat top. The averaged, estimated SEAT values were compared to averaged measured values and two values have similar trend.
The subjective ratings were obtained using a paired comparison methodology, called virtual seat method, that eliminated static comfort bias during the evaluation. The results indicated that there is similar trend between the subjective ratings and the SEAT values when the subjective ratings and transmissibilities are averaged over the six subjects. Both results show that Seat B is better than Seat A in terms of dynamic comfort.
