Hearing Levels of Youths 12-17 Years, United States. National Health Survey Series 11, No. 145.
National Center for Health Statistics (DHEW/PHS), Hyattsville, MD.
The report of the National Center for Health Statistics presents national estimates of the hearing levels of youths 12-17 years of age in the civilian noninstitutionalized population of the United States. These are based on individual monaural, puretone, audiometric test results of eight frequencies as obtained in the Health Examination Survey of 1966-70 for a national probability sample (N=6,768) representative of the 22.7 million youths in that segment of the population. Age, sex, race, region, urban-rural, income, and parent-education differentials in hearing levels are assessed. Major findings summarized from the study among youths include: that for their better ear more than half had hearing thresholds below (better than) the American Standard Association (ASA) 1951 standard for audiometric zero at all frequencies tested except 6000 Hertz; that hearing levels for girls are generally lower (better) than among boys, by mean differences large enough to be statistically insignificant at 2000-8000 Hertz; that the prevalence of hearing handicap as estimated from the puretone audiometric test results in this survey is quite low (only about 1.5 percent, or an estimated 281,000 youths 12-17 years of age in this country, have some degree of hearing handicap); and that youths from families with less than $5,000 per year had higher mean thresholds (poorer hearing) than those from families with income of $5,000 and over.
