30 THE TALKIES sound-recorder has to face, because it means that unless he is very careful about the dimensions of the various sections of his sound-recording apparatus, he will find that certain notes will be reproduced more loudly, and others more weakly, than they ought ; producing, for instance, among other symptoms, the effect of someone speaking through their nose. The early gramophones sounded tinny and horny for at least two reasons, the first being that the reproducing arrangements were frightfully resonant because the dimensions of the various pieces they were composed of made them reproduce some notes too loud and ignore others ; the second being that they had very short horns, which made it difficult for the lower notes to emerge at the same strength as the higher ones. Scientists have shown that if you really want to make a horn that will do justice to the lowest notes, it must be at least 7 or 8 feet long. The problem of getting such a bulky affair into the cabinet of a gramophone has been overcome by curling the horn round itself, the famous "His Master's Voice" Re-entrant horn being the most perfect example.
