...behind Mr. Dixon's original idea, which was to celebrate completion of San Francisco's two great bridges. Chosen president of the fair corporation was Leland W. Cutler, who is no gardenia-fragrant showman like New York's Grover Aloysius Whalen,* yet is just as sound a financier and heady planner. An engineer named William Peyton Day made cruise after patient cruise taking soundings of the shoals north of Yerba Buena (Goat) Island, perfecting the idea of pumping up out of the Bay's black bottom a site for the fair which could later serve...
...promote the recent Dallas and San Diego fiestas. He turned a futuristic, local conception into a glamorous fairyland motif with the slogan: "See All the West in '39." That brought in all California's neighbor States. It wowed the transportation companies. And it was based on the sound perception that, whereas whole families stayed in town for weeks to see San Francisco's marvelous 1915 exposition, the average stay of today's streamlined travelers is two and one half days...

What does demand solution is why, when Hollywood can make pictures as sound as Made for Each Other, it practically never does...
...Hardinge's son, Harlowe, vice president and general manager of Hardinge Co. of York, Pa., studied his father's "ball mill" in operation. There was a certain rate of feeding in ore at which it performed most efficiently, and that rate could be estimated by sound. When the feed was too slow, the noisy clatter of the mill increased; when too fast, the sound was muffled. Workmen were trained to listen for these changes in sound and manipulate the ore flow accordingly. But Harlowe Hardinge noticed that the listeners' judgment was likely to vary as much...
Harlowe Hardinge therefore invented a sensitive "electric ear" to replace human hearing. A parabolic reflector picks up the sound from the mill, focuses it on a microphone. If the sound is at the most efficient level, the microphone current keeps a galvanometer balanced between two contacts. If it rises or falls as little as one-quarter of a decibel, the galvanometer makes contact on one side or the other, closing a circuit which starts or stops the flow of ore as the situation requires. More than 75 of these electric ears are already...
