HIS 230 Final Exam Study Guide

Think about all of the components of the hearing evaluation and how you should interpret and use the information.

History:

- What are the medical red flags you should be listening for in the answers to the questions?
- What type of information is important in their communication history?
- Why is it important to get the case history information?

Test Environment:

- Why is it important to have an appropriate test environment?
- What happens when you don’t have an adequate test space?
- Why are sound treated rooms beneficial for test environments?
- How do you seat the client for testing?

Equipment:

- Do you understand the different between headphones and insert phones and why the interaural attenuation is different for each?
- Most of the rest of equipment questions was in your first audiometry course so I am not going to go back and cover it.

Otoscopy:

- Why is it important to do?
- What types of things or conditions can you see in an ear?

Pure Tone Air/bone Conduction:

- I will ask more about what to do with the information and about masking than the basic pure tone procedures.  Again you should be comfortable with the procedures for obtaining pure tone air and bone conduction thresholds since you covered that extensively in the first audiometry course.

Speech Testing:

- Speech Recognition Threshold- the key is the word threshold.  Make sure you know the procedure for obtaining an SRT.  What materials should be used?
- Word Recognition Score- How is the procedure done?  What materials are the most commonly used.  25 or 50 word lists and why.
- For both procedures know the difference between using monitored live voice and recorded materials.  Why would you do one or the other?  What is the recommended best practices way to do the procedures?

Most Comfortable Listening Level:

- What is the procedure for obtaining the MCL?
- What materials should be used?
- How is the information used?  Why do you obtain this information?

Uncomfortable Loudness Level:

- What is the procedure for obtaining the UCL?
- What materials should be used?
- What is the difference between obtaining a Speech UCL and frequency specific LDLs?
- What is the best practices way of obtaining this measure?
- Know what is required on the Missouri state licensing exam vs. best practices.  We talked about this in labs last week.  Sometimes there will be differences in what you have to answer on the test and what your instructors believe is the best practice.  We want you to understand the difference between a Speech UCL and frequency specific LDLs.  Missouir requires you to do a Speech UCL to pass the exam.

Immpedance Audiometry:

- Understand what a tympanogram is measuring.
- Understand the five basic types and what they are indicating.
- Understand what makes an acoustic reflex happen.
- Understand what ipsilateral reflexes mean for the different types of hearing loss.

QuickSin:

- How is the procedure done?
- How is it scored?
- What materials are used for the test?
- How should it be used in recommending amplification?

Acceptable Noise Level:

- How is the procedure done?
- How is it scored?
- What materials are used for the test?
- How should it be used in recommending amplification?

Masking:

- What are the rules for masking air conduction testing?
- What are the rules for masking bone conduction testing?
- What are the rules for masking Speech Testing?
- How much masking should be applied in each of the above situations?
- What is the plateau method?
- What is effective masking?
- What is overmasking?
- What is interaural attenuation and how does it differ for AC and BC and headphones vs. insert phones?

Types of hearing loss and possible causes:

- Know the difference between sensorineural hearing loss, mixed hearing loss and conductive hearing loss.
- Where is the potential “site of lesion”? Outer ear, middle ear, inner ear or more central.  A general idea.  You don’t need to memorize all the causes just have a general idea of what are potential causes for each part of the ear.  For example can earwax affect hearing?  I won’t ask vague or difficult questions on this topic.

Other test you read about or watch videos:

- Contralateral acoustic reflexes
- Reflex decay
- OAEs
- These were mostly for informational purposes.  Audiologists use these tests for additional “site-of-lesion” information.  It was to give you an idea of what other tests are available.  Also for the few that may be interested in additional education in the future.
- I won’t ask any questions on the final about these tests.
