Auditory Function Tests

3.2.1 Describe in detail the decibel scales used to measure sounds and hearing (dB HL, dB SPL and dB SL).

3.2.2 You practice in Timbuktu (no audiologists to be found). Tell us about tuning fork tests…how are they done and how should they be interpreted?

3.2.3 What is the speech reception threshold (SRT) and how is it measured?

3.2.4 How would you test speech discrimination?

3.2.5 Masking…what is it, why do we do it? What is a masking dilemma?

3.2.6 Be prepared to draw and describe the classification of tympanograms.

3.2.7 Educate us on the acoustic reflex. What does it mean if there is “no response”?

3.2.8 What is the auditory brainstem response (ABR)? How is it measured and what are the limitations?

3.2.9 Give us a mnemonic for the ABR wave forms.

3.2.10 Describe special techniques used in the evaluation of hearing in the pediatric population.
