In this study an objective metric is presented to evaluate the hiss noise of hydraulice power steering. The correlation between subjective tests and psychoacoustics metrics is investigated. The objective metric is obtained using multilinear regression where the psychoacoustics metric and the results of the subjective tests are the dependent and independent variables of the linear regression, respectively.

The application of sound quality tools in the design process of electro-hydraulic power steering (EHPS) is investigated in this paper. The EHPS acoustics performance is investigated by studying the correlation between objective measurements and subjective evaluation of the noise from the EHPS.

This paper studies the transmission loss of bounded double panel lined with poroelastic medium. Hamilton variational principle is used to derive the equation of motion. Kirchhoff hypotheses are assumed for the displacement field of the panel and Biot constitutive equations are used to model the poroelastic core. Resonant and non-resonant sound transmissions are investigated. Equivalent stiffness constants of the panel are presented. The results of the transmission loss based on the derived equation are compared with classical results.
