Course: 14SU-HIS-230-GH101-ADVANCED AUDIOMETRY > Section: Lessons

This quiz is on speech testing and masking.

Q: The IA for pure tones presented under headphones is 40dB.
- True
- False
A: True

Q: The IA for pure tones presented by air conduction through insert phones is 40dB.
- True
- False
A: False

Q: Narrow band noise is the same as white noise.
- True
- False
A: False

Q: You don't have to mask for bone conduction if
- air conduction thresholds for the right and left ears are within 15dB of each other
- air conduction thresholds are normal
- air conduction thresholds are the same in both ears
- none of the above
A: air conduction thresholds are normal

Q: Bone conduction must be done even if air conduction thresholds are normal.
- True
- False
A: False

Q: IA for pure tones presented through insert earphones is
- 70dB
- 65dB
- 45dB
- 60dB
A: 70dB

Q: You have obtained a bone conduction threshold with masking at 1kHz and found there is no air bone gap.

You should:
- skip bone conduction testing for the rest of the frequencies since no air bone gap was found at 1kHz
- test 2kHz and if no air bone gap is found stop BC testing at this point
- obtain thresholds for the rest of the BC test frequencies
- any of the above are acceptable if no air bone gap is found at 1kHz
A: obtain thresholds for the rest of the BC test frequencies

Q: Thresholds are recorded on an audiogram in:
- dBSPL
- dBSL
- dBHLA
- dBHL
A: dBHL

Q: IA for bone conduction can be as high as 20dB if the client has a thicker than average skull.
- True
- False
A: False

Q: A 50 word spondee list should be used to determine the client's SRT.
- True
- False
A: False

Q: Spondee words are _______ syllable, phonetically balanced words.
A: two

Q: One of the presentation levels recommended for word recognition testing is MCL plus 5-10.
- True
- False
A: True

Q: You do not need to mask for SRT (speech reception threshold testing).
- True
- False
A: False

Q: Using a 25 word list for WRS (word recognition testing) is as reliable as using a 50 word list.
- True
- False
A: False

Q: The SRT should be in good agreement with:
- the PTA (pure tone average) at 500, 1000 and 2000 kHz
- the PTA at 250, 500 and 1kHz
- either of the above
- neither of the above
A: the PTA (pure tone average) at 500, 1000 and 2000 kHz

Q: You have obtained an SRT (speech reception threshold) when the client can repeat the ords correctly 50% of the time.
- True
- False
A: True

Q: The purpose of the SRT (speech reception threshold) is to make sure the client can follow directions for pure tone testing.
- True
- False
A: False

Q: Masking is not necessary for word recognition testing if TDH headphones are used.
- True
- False
A: False

Q: Masking should be used for word recognition testing if the presentation level in the test ear and the bone conduction threshold in the nontest ear differ by 45dB or more.
- True
- False
A: True
