Public Visit YA Studios

BENLY curious as to the how and the why of broadcasting, niany listeners are availing themselves of the opportunity of visiting the studios. For long they have been at the receiving end and they have been puzzled by the mystery of how sound can be carried by perfectly soundless waves from the studio to their homes, 80, when the opportuuity of being shown over the studios has presented itself, the invitation has been accepted with alacrity. Some are now more informed on the technical side, some are not, but all have enjoyed the visit immensely. They have at any rate seen where the broadcasting starts from, even if thegpdo lose track of the sounds while travel from the aerial to theim eqc™R ing sets, and are somewhat at a loss to * explain why they should then again be audible from a loudspeaker. Of course, to all, the way in which a studio concert is "staged’’ has been most interesting. They have seen the little microphones whose tireless ears absorb all that the artists sing or play. They have found it interesting to attempt to trace the conversion of energy from the singers to the re-creation of their voices in the homes of thousands of listeners throughout New Zealand and overseas. And, as they have thought of it all, they have marvelled. When an artist sings he causes mechanical vibrations ef his vocal chords, which produce sound. The sound strikes the microphone and causes an electric current to be pro- , duced, which is exactly like the sound. , This is amplified many times and* caused to modulate or mould the high frequency carrier wave of the transmitter in accordance with the electrical low frequency current produced by the microphone, This high-frequency modulated current is supplied to the antenna, from where it is radiated into space in the form of electrical magnetic waves. These waves travel with

the speed of light to the receiving sets, where they are changed to low frequency currents, so that they can operate a loudspeaker. This means that the electrical energy is converted into sound and radiated on the air to the ear in the form of sound waves identi-cal-or should be, if the set is efficient -with the sounds emerging from the mouth of the singer in the studio.
