These methods included reviewing written information from NIOSH, conducting site visits to facilities operated or used by NIOSH, inviting comments from stakeholders, and hearing presentations at two information-gathering meetings. INFORMATION GATHERING Written Information from NIOSH The NIOSH Hearing Loss Research Program provided a roughly 400-page notebook of information to the committee in advance of the committee's first meeting.

Opportunity for Stakeholders to Comment on the NIOSH Hearing Loss Research Program The committee was directed by the Framework Document to consider stakeholder input in assessing the impact and relevance of the NIOSH Hearing Loss Research Program. Issues of interest included whether stakeholder input was taken into consideration in shaping the NIOSH research program and stakeholders' views on the program's research activities and products.

Working indepen dently and drawing on suggestions from committee members and staff research, the committee identified as possible stakeholders individuals and organizations with an interest in audiology, hearing conservation, hearing protection devices, noise control engineering, and occupational epidemiologic research. This group included researchers from academia and private organizations, professional soci eties, organizations representing labor and industry, and others who deal directly with occupational hearing loss or were considered likely to be aware of this issue.

However, the comments provided to the committee gave helpful insights on responders' perspectives toward the NIOSH Hearing Loss Program and informed the committee's understanding of the program's relationship with some of its stakeholders. Stakeholder Comments on Emerging Research Needs or Opportunities To assist the committee in reviewing stakeholder input, the staff compiled the comments on significant emerging research needs or opportunities.

As part of our effort, we are seeking input and advice from a variety of individuals and organizations that we believe are likely to have an interest in occupational hearing loss and noise control. The committee's charge is to examine the following issues for the NIOSH Hearing Loss Research Program: (1)
