...Irving Berlin, Doin' What Comes Natur...
...College, Cullinane had studied applied mathematics and computer sciences. He had traveled to Berlin in 1978 as a trumpet player in the Harvard-Radcliffe Orchestra...
Then, at age 27, she met Charles I. Berlin, an audiologist who heads the Kresge Hearing Research Laboratory of the South in New Orleans. Using special equipment, Berlin was able for the first time to provide a precise diagnosis of Kam's problem: "ultra-audiometric" hearing, that is, the capacity to hear, but only at extremely high frequencies...
People with ultra-audiometric hearing, says Berlin, are usually born with full-range hearing, but become deaf in the lower registers after suffering a high fever, virus or meningitis in childhood. Some have an extended upper auditory range and can hear dog whistles or the shrill hiss of a department-store electronic security system. Their problem, as in Kam's case, generally goes undetected because of inadequate testing. Most testing devices do not produce sounds above a certain frequency, Berlin says, "and it is precisely at this cutoff that ultra-audiometric patients begin hearing." Worse still, ultra-audio-metrics...
...case was one of several that prompted Berlin to begin developing a hearing device that would "translate" low-frequency sounds into the range at which ultra-audiometrics could hear them. With help from engineers at the Illinois firm of Knowles Electronics, he produced a miniature magnetic earphone with two channels. One channel amplifies high-pitched sounds; the other shifts lower pitches upward into the range heard by ultra-audiometrics. The earphone is wired to a battery pack and microphone...
