Learn More About Hearing Conservation

Hearing conservation is the prevention of hearing loss.  Although traditional hearing conservation efforts have focused solely on noise in the workplace, the goal of the National Hearing Conservation Association (NHCA) is to prevent ALL hearing loss - whether it results from workplace noise or other environmental factors - in all sectors of society.  NHCA strives to be the premier resource for individuals involved in hearing loss prevention.

Resources in Hearing Conservation

NHCA has worked with the Occupational Safety and Health Administration (OSHA) to develop an "e-tool" on hearing conservation which is now available on the OSHA website.  OSHA also has other materials available on noise and hearing conservation.

The National Institute for Occupational Safety and Health (NIOSH) has a useful page onWork-Related Hearing Loss, and has created two particularly helpful documents on noise and hearing loss:

  • "Preventing Occupational Hearing Loss - A Practical Guide." 1996, edited by John R. Franks, Mark Stephenson, and Carol Merry, published by the U.S. Department of Health and Human Services. (Publication No. 96-110). Provides checklists and other information for evaluating hearing conservation programs.  Available in print and onlineat the NIOSH website.

  • "Occupational Noise Exposure Revised Criteria 1998." 1998, published by the U.S. Department of Health and Human Services (Publication No. 98-126).  Provides recommendations for best practices in hearing conservation programs.  Available in print and online at the NIOSH website.

NIOSH also provides many other useful documents and materials on hearing conservation.  These include:


Hearing Conservation Assistance from NHCA

There are a number of NHCA members who provide consulting services, including guidance on developing hearing conservation programs and materials.  In addition, NHCA has developed educational materials on hearing conservation, including a series of practical guides on hearing conservation topics.  The NHCA website contains a searchable bibliography on hearing conservation-related materials (courtesy of Elliott Berger at E-A-R) which includes hundreds of useful articles on noise and hearing loss.  The website also contains information on various hearing conservation regulatory requirements.  NHCA has recently published an electronic series of Practical Guides on hearing conservation. NHCA is currently working to develop a model hearing conservation program for several industries, including construction.


Learn about Hearing Conservation at the Only National Hearing Conservation Conference in the US

One of the best opportunities for learning about effective hearing conservation programs and efforts is the annual NHCA conference.  The 2010 NHCA conference will take place in Orlando, FL from February 25-27, 2010.  This conference represents an excellent opportunity to meet other hearing conservation professionals and to get updated on the latest research and best practices.


Hearing Conservation Information Available Only to NHCA Members

Membership in NHCA provides access to a number of useful members-only resources, including Spectrum, the publication of NHCA, proceedings of previous conferences, access to draft guidelines and recommended practices, a searchable online membership directory, and more.

There are a number of other organizations involved in hearing conservation-related efforts.  However, NHCA is the only organization dedicated to preventing hearing loss from all sources.
