Abstract

A Comparison of the Predicted Dynamic Stiffness of Resilient Layers with Calculated Values Obtained from the Measured Acceleration Response

Michael. A. Stewart and Robin. K. Mackenzie

Omissions have occurred in Equation 4 and Equation 11 on pages 300 and 301 respectively, for which the Editors and Publishers of Building Acoustics apologise.

Equation 4 should read:

$\frac{a_2}{F_1}=\frac{-\left[\bar{\text{K}}(1+j\eta )\right]}{{\omega }^2{m}_1{m}_2-\bar{\text{K}}(1+j\eta {)(\text{m}}_{\text{1}}{+\text{m}}_{\text{2}})}\left(\frac{m/s^2}{N}\right)$ (4)

Equation 11 should read:

$c_l=\sqrt{\frac{K_{0}d}{\rho S(1-{\mu }^2)}}\hspace{0.17em}(\text{m}/\text{s})$ (11)
