AIR TRAVEL
■PLANS TO -LESSEN NOISE. (British, Official Wireless.) (Rec. 5.5 p.m.) Rugby, September 20. A careful investigation of the methods whereby air travel can be made less noisy is being undertaken by the Aeronautical Research Committee. It is of the opinion that this will have to come largely from a lessening of the sources of noise, namely, by a reduction of the air screw tip speed, by a silencing of the exhaust, and by a silencing of engine noises due to tappet rods etc. Some improvement is also possible by the construction of cabins with inner and outer sells packed between with woolly fireproof insulator. This type of wall construction is being used on British civil air liners.
