| (12) The bugbear of steel construction has always been resonant noise in the body. But intensive acoustic studies are beginning to reveal the sources of this and the day is close when all steel cars will have just as good noise characteristics as the best "custom-tailored" motorcars. Steel construction is the only way we know to build cars which can never "loosen up". One can see that on R.R. cars there will always be a demand for "special" jobs, so that an "underbody" capable of carrying a touring car would have to be included in every model of car. This could be similar to a bare chassis but more scientifically designed and of lighter gauge metal than the conventional chassis. | ||
