Prior to now decade there was a dramatic switch within the nature of cellular communications expertise and its influence at the normal communic ations setting. within the Seventies, cellular radio was once a minority job in communications, according to rather unsophisticated expertise. The Nineteen Eighties, even if, have noticeable the emergence of analogue mobile platforms and the definition of destiny electronic platforms, and the anticipated call for for those prone is such that investigations into using greater frequency bands have already all started.

Although the pattern of change is less clear-cut than for fundamental frequency, Table I indicates a slight decrease during the period of vocal maturation, a reduction from young adult to middle age, followed by an increase in men aged 80 and over. Maximum pitch range may also be affected by advanced age. When the performance of men over 65 was compared with that of men under 40, maximum pitch range of the older Table I. 3 PHONATORY AND RESONATORY PROBLEMS OF ORGANIC ORIGIN 27 group was four tones less than the range of the younger group (Ptacek, Sander, Maloney, & Jackson, 1966).
WILDER listeners' perception of speaker age. However, investigation of age-related aspects of the male voice has been confined largely to fundamental frequency. Table I shows a progressive lowering of fundamental frequency from Fairbanks's finding (1942) of a mean of 556 Hz for a male infant cry to the mean speaking fundamental frequency of 107. 5. 3 reported for males in their eighties (Mysak, 1959; Hollien & Shipp, 1972). In short, the aging trend for males with respect to pitch central tendency is one of a progressive lowering of pitch level from infancy through middle age, followed by a progessive rise in old age.
