...aircraft's four Allison turboprop engines. The birds' bodies clogged the turbines so that power was insufficient to keep the Electra airborne. Two Federal Aviation Agency scientists had already raised an eerie possibility. Wrote they after studying sound patterns: "The Electra sound spectrum contains an audible chirp which appears identical in frequency and wave form to the chirp of field crickets. Field observations strongly indicate that the sound of the taxiing Electra exerts an attraction for starlings, and possibly other birds, particularly in the fall in the Northeast, when insects suddenly become less plentiful...
...Chirp-chirp, says Burwell, means a pain in the fan belt or the generator...
Thunderous Chirp. Far from being alarmed, acoustical engineers today are in favor of the low steady hum. "There should be an unobtrusive noise, constant and surflike," says Robert B. Newman, a partner in the Cambridge. Mass., acoustical engineering firm of Bolt, Beranek & Newman, Inc. Without it, the slightest sound can prove enormously distracting. Typical is the commuter who reads a book amid the accustomed clatter of the 5:42, yet is shaken out of bed when a robin chirps in the silence of a country morning...
...Conductor Hans von Bulow was so moved by Edison's handiwork that when he heard a recording of himself playing a Chopin mazurka, he fainted dead away. In the early days Columbia slipped commercials in between the musical selections on its cylinders, forcing the listener who bought the Chirp, Chirp polka to endure a sales pitch for men's overcoats. Columbia, also in those early days, considered the phonograph to be a potential boon to the illiterate. Instead of giving themselves away in writing, suggested Columbia, people could record their messages on a cylinder and ship it through...
...faint chirp of the airborne radio has been followed for only 25 miles, and the Navy has added little to its pigeon lore. But seagoing scientists have far more ambitious experiments in mind. Porpoises, another animal uncannily clever at navigation, will be fitted with larger transmitters in the hope of learning how the aquatic mammals set their course. Eventually, the Navy hopes, its little radios will signal defeat for an ancient enemy: the albatrosses (known as gooney birds) that nest by the thousands on Midway Island and make its runways dangerous for aircraft. Naval experts on bird migration suspect that...
