Title: 1.4 Quiz on Last Semester's Material
Course: 14SU-HIS-230-GH101-ADVANCED AUDIOMETRY

This is a quiz reviewing material we visited in our previous semesters and in the readings for this course in the first week.

The quiz is a mixture of true/false and short answer questions.

Your participation is worth 50 points.

You should have completed this quiz and submitted it in the dropbox no later than Saturday, August 24, 2013 at 11:59pm

You have one hour to complete this quiz. You are allowed to see only one question at a time and you are not allowed to "backtrack".

Q: If you submit work more than one week late, you may receive a failing grade.
- True
- False
A: True

Q: If you submit an assignment/quiz/discussion post within in one week after the due date, you may receive a grade reduction.
- True
- False
A: True

Q: We have been taught to determine a pure tone threshold using the bracketing technique.
- True
- False
A: True

Q: If you are testing in the same room as your patient, you should position the patient so that he cannot see your hands
- True
- False
A: True

Q: We start our pure tone testing at 1kHz because this is a familiar sound.
- True
- False
A: True

Q: You can determine your patient's better cochlear by using the audiometric Weber test.
- True
- False
A: True

Q: What is the reference for dBHL?  In other words,  if there is a value of 50dBHL, it means 50dB above what?
Feedback: Normal hearingthreshold or audiometric zero established for a large group of yound adults. This is the average lowest level of sound at which this large group of people could just barely hear a tone of that frequency 50% of the time.

Q: How would you define a transducer?  And give me an example of one.
Feedback: A transducer is something that changes energy from one form to another. An example if a TDH earphone.

Q: If we have a tone that it 50dBSPL. what does that mean?  50dB above WHAT?
Feedback: Above .0002dynes/cm3 or the softest sound heard by the very best human ear in the very best conditions.

Q: If we present a tone that is 50dBSL, what is that reference level....50dB above what?
Feedback: The patient's threshold for that stimulus.

Q: The IA for bone conduction pure tone testing is 40dB
- True
- False
A: False
If right: It's 0 dB - the generally accepted value

Q: List five things that you can control with an audiometer.  (We are not talking about "power on/off" or plugging in the headphones or bone oscillators.  I want you to tell me about the dials and buttons you can control.
Feedback: intensity talk back talk forward pulsed/constant warble/constant frequency stimulus (speech, cd, mic,pure tones, noise) test ear others

Q: Lise three things you will be doing in a daily LISTENING check of your audiometer. ( Note:  We are not worried about frayed or cracked cords and we know that the power switch works.)
Feedback: linear steps in intensity frequencies are true switches left to right CD provides speech stimulus no other sounds through headphones. more

Q: We test five octave in a basic pure tone test.
- True
- False
A: True

Q: For pure tone assessment using masking, we should use narrow band noise
- True
- False
A: True
