CLEAR SPEECH.

TECHNIQUE OF ’PHONE USE. THE MOST EFFECTIVE METHOD. 1 New Zealand ranks high in the world as a telephone-using country and its equipment for this purpose is kept thoroughly up-to-date. However, an efficient system will not produce satisfactory results unless sensitive electrical apparatus is used in ihe most effective way. The Post OlTlce is, preparing some illustrated advice to lie published in its telephone directories on how to make the telephone conversation clearer and easier. The engineers having done their part I In providing instruments and efficient transmission lines tlie user of tin* telephone can then get the best results only by speaking so closely into ttie transmitter that Ihe lips almost touch it. Human speech causes sound waves I which impinge on a diaphragm placed ! just inside the transmitter and thus i i electrical impulses are created which j are carried along the lines and turned j again into sound-waves at the receiv--1 I ing end. The more effective Hie transj mitt ing end the stronger are these electrical impulses which must be turned again into sound waves. Shunting into the telephone is not necessary in these days of sensitive instruments. The greatest temptation I to do so is when the parties to a conversation are separated by hundreds of miles, lull if they realised that at intervals along New Zealand’s main telephone trunk lines are electrical reI pealers which boost, up Ihe impulses 1 ! Ihe shouting tendency would disappear. I Speaking close to the transmitter also • | gives I lie advantage of reducing the > I effects of any extraneous noises. ’ i There is no danger to health inI j volved by Hie use of the same transmitter by large numbers of people, for j this point, lias been subject to careful ' j bacteriological tests with completely negative results.
