Introduction to Dangerous Decibels

How to use these Dangerous Decibels’ materials

These resources are a supplement to the “Dangerous Decibels Classroom Program” and provide a series of hands-on, minds-on science activities for the K-12 classroom or intro university course. These activities may be done prior to or after the classroom program. Some may be incorporated into the classroom program if time is available. The activity format has been teacher-tested. Care has been taken to provide content explanations for the teacher or interested gifted student who wants to explore further. In addition to rich science content, each lesson emphasizes the behaviors needed to reduce the risk of noise-induced hearing loss, as well as grade-level appropriate science process skills. Because teachers may choose to do only one activity, you will find some redundancy in the content and behavioral messages from one activity to the next. You will find that all activities in this Resource Guide:

  • are safe
  • are affordable
  • are practical and easy to use
  • have been classroom tested
  • are supported by rich content
  • have been reviewed by K-12 teachers
  • have been reviewed by science content specialists
  • have been reviewed by hearing specialists
  • were tested in primary, intermediate, and middle school classrooms
  • have been aligned with national science standards
  • are linked to the behavioral objectives of Dangerous Decibels

For your convenience the curriculum is organized into detailed, easy-to-follow sections found below with individual sections designated.
