Hs.{Lord Ernest Hives - Chair} and Rm.{William Robotham - Chief Engineer} both emphasised the fact that the silence of the present day American car is obtained largely by the ingenious use of sound deadening materials such as felt, cardboard and rubber, and that the mechanical noise of the chassis is shut out by well lagged and tightly packed flooring, and dash curtains of sound absorbing material.

Rm.{William Robotham - Chief Engineer} said that a comparative test of the Buick and a Bentley with floor boards removed proved the Buick to be the noisier car of the two.

It was agreed to meet again at 3.p.m. on Monday, February 18th, to further review progress on SpectreCodename for Phantom III.
