Limitations Of Selected Frequency Audiometry In The Public Schools

Abstract
3,630 Oto-chek tests in the Greenwich Public School system in a 1-year period showed that the audiometric frequency showing the greatest loss is not at 4000 cps. Screen testing limited to 2000 and 4000 cps frequencies will fail to detect a significant number of children with hearing losses. A 3-frequency test including 1000, 2000, and 4000 cps is almost as efficient as a complete 5-frequency sweep check, but the amount of time saved is negligible.
