| -2- These drives are still very noisy and we think that a determined effort should be made to adopt some means of quietening same. It has occurred to us that if the outside of the cable casing was lagged by moulding on a thick rubber covering (i.e. 1/8"), the noise of the cable would be considerably reduced. We should like to know if you have carried out any experiments in this direction. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
