英语词汇decibel的起源、历史背景-英语词源词典

decibel. “Watson, come here; I want you.” These were the un- dramatic words spoken by inventor Alexander Graham Bell to his lab assistant on March 10, 1876, the first complete sentence conveyed over the telephone. Bell was a Scottish immigrant who in 1871 came to the United States, where he lectured to teachers of the deaf on his father’s visible speech method and opened his own school of vocal physiology in Boston. In the course of work on his harmonic telegraph, he invented the first practical telephone, an idea he had conceived as early as 1865. Later inventions included the first practical phonograph record, the audiometer, and a telephonic probe for locating bullets in the human body. The Bell Telephone Company was formed in July, 1877. The inventor died in 1922, aged 75. Bel, a unit of measuring the loudness of electrical signals, and decibel, 1/10 of a bel, both honor his name.
