Specific Purpose:  To inform my audience on how to choose hearing protective devices.
Attention Getter:  Evidence:  According to the Hearing Alliance of America, “more than 24 million people in the United States have a significant loss of hearing”.  Although some of these cases are caused by age, a great number of them, approximately 10 million, according to the National Institute for Occupational Safety and Health, are caused by exposure to loud noise—the same types of loud noise we expose ourselves to every day.  Simply choosing appropriate and recommended hearing protection devices can help prevent such hearing loss.
Statement of Central Idea:  Successful selection of a hearing protective device involves choosing the correct type, knowing if it provides enough protection, and making sure it will be comfortable to wear.
Tie to Audience:  Safety hearing protective devices are necessary at both home and work.  Even when mowing the lawn or using loud power tools can cause hearing loss.
Credibility Statement:  As a Certified Occupational Hearing Conservationist by the Council for Accreditation in Occupational Hearing Conservation, I have received extensive training and have several years of experience in the proper selection and use of hearing protective devices.
Preview of Main Points:  Today I will show you how to tell the difference between the different types of hearing protective devices, how to tell what will provide the correct amount of protection, and the importance of comfort in your selection.
