Procedure

Students will design their own protective hearing device. Use these steps to aid in the design.

  1. How can we stop sound from entering our auditory system? What blocks out more sound, covering our ears with our hands or plugging our ears with our fingers?
  2. Examine the properties of current protective hearing devices. What materials are they made out of? Why are those materials used?
  3. Is your design practical and comfortable? In what situations are protective hearing devices needed? Can you go about your daily routine wearing the device?
