Industrial hearing conservation programs are assessed in terms of the extent of existence, standard practices, problems encountered, and apparent measures of effectiveness. A survey questionnaire was used and site visits were made in order to elicit responses from individual companies in four major industrial categories: manufacturing, construction, transportation and mining. The results indicate that many industries are responding to the need for establishment of hearing conservation programs. Of those companies claiming to have noise problems, the majority have noise reduction programs and a large percentage are planning such programs. Engineering noise control seems to pose the greatest problem for industry, and most companies deal with controlling noise exposure through the use of ear protectors. Tolerances on audiometers and on background noise levels in test rooms as established by the American National Standards Institute were frequently exceeded at one or more frequencies, indicating a need for more precise calibration check procedures. Forms and specification sheets provided by some of the companies which were interviewed are presented in several of the appendices to this report. Also, the contents of the questionnaire and data from the calibration checks are included.
