To prevent noise-induced hearing loss, they have joined with many organizations in a national effort to educate the public about ear defense. This education effort has a special emphasis on children and persons in the workforce. In addition, the Occupational Safety & Health Administration (OSHA) mandates that employers provide hearing conservation programs for their employees in workplaces where noise levels equal or exceed 85 decibels for an 8-hour time-weighted average.18 Many States have OSHA-approved State plans and have adopted their own standards and enforcement policies. << Previous—Progress Toward Healthy People 2010 Targets | Table of Contents | Next—Emerging Issues >> |
