Scope note(s)

  • The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.

These interviews begin with Davis’s studies at Harvard and his post-graduate study in England. Davis discusses his research on the electrophysiology of the auditory system and electrical activity of the brain and his defense work during World War II studying human tolerance to loud sounds. Davis describes the establishment of a research department at the Central Institute for the Deaf and work on hearing tests and speech audiometry, including the development of the first American standards for audiometers. Davis describes then-current methods in electro-physiology to measure peripheral hearing of young children by detecting electrical responses in the brain. The interview ends with a brief discussion of the problems related to world overpopulation, pollution, and international relations.

The transcript presents an edited version of the sound recording. The interview begins with a biographical sketch of Hallowell Davis, and ends with a revised biographical sketch. Interviewed by Estelle Brodman on April 6, 1977 and April 28, 1977. OH027. Approximate Length 2 hours, 45 minutes.
