Activity 1.3.2 Can You Hear Me Now? Introduction In the last activity, you learned what can go wrong in the ear to cause different types of hearing loss. Hearing tests are the first step toward understanding hearing loss. There are several different hearing tests that can be done to determine the type and extent of one’s hearing loss. Once the hearing loss has been determined, the most appropriate intervention(s) can be identified to help the person regain as much normal function as possible. In this activity you will perform a variety of different hearing tests. You will then explore the various interventions available to help patients cope with hearing loss and make a recommendation as to what intervention is the most appropriate for your hearing loss patient from the previous activity. Procedure Part I: Hearing Assessment Please note that the hearing assessments used in this activity are not meant to be diagnostic tools to detect hearing loss. Hearing should only be tested by qualified professionals. Rinne Test 1. Obtain a 512 Hz tuning fork and a stop watch. 2. Go to the following website. Click on View QuickTime Movie to watch a short video of someone performing the Rinne Test of a subject. Note that the video may take a few minutes to load. o Webster University – The Rinne Test 3. Work with a partner. Have one partner act as the subject and sit with his or her eyes closed. The other partner will act as the tester. The tester will complete Steps 4 – 9. 4. Strike the tuning fork on your wrist or the sole of your shoe, causing it to vibrate. 5. Place the end of the tuning fork’s handle against the subject’s mastoid process (the bone directly behind the bottom of the subject’s earlobe). Make sure that the prongs of the tuning fork are pointed downward and away from the ear. Begin timing with the stop watch. 6. Ask the subject to indicate when the sound is no longer heard. Time how long the subject can hear the sound generated from the tuning fork. The sound sensation is that of bone conduction. Record the measured time in Data Table One. © 2010 Project Lead The Way, Inc. Medical Interventions Activity 1.3.2 Can You Hear Me Now? Logger Pro – Page 1

7. Remove the tuning fork from the mastoid process and immediately position it so the prongs of the tuning fork are pointing into the ear. Resume timing with the stop watch. 8. Ask the subject to indicate when the sound is no longer heard. Stop the stop watch when the subject can no longer hear the sound generated from the tuning fork. Determine how long the subject heard the tuning fork when it was pointing directly into the ear. This sound sensation is that of air conduction. Record the measured time in Data Table One.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
