Facts About Hearing Found In Laboratory Tests
At Bell Telephone Laboratories in New York scientists used vacuum tube oscillators and special receivers to measure ear sensitivity. The range from the faintest auditable sound to the loudest non painful sound spans about ten octaves from roughly 20 to 20 000 cycles per second. The ear shows greatest sensitivity between 1 000 and 5 000 cycles, with high pitched tones often more detectable. Audiometers were perfected for testing hearing and assessing loss, aiding speech clarity in telephone connections.
