title: Hearing threshold levels according to age.
abstract: Over 2900 audiograms from employees of a large food and drinks manufacturing company are reviewed. Hearing threshold levels according to age are tabulated and these appear to be different from the previously recognized average hearing threshold levels. There was no selection of these cases and include all otological and other hearing defects. The hearing thresholds therefore represents an unbiased sample of an industrial population.
