1. Immittance testing (tympanometry and acoustic reflexes) forms part of the standard audiometric test battery. Describe the different types of tympanograms and provide examples of the aural conditions that may accompany each. Describe how acoustic reflex testing adds to this information.
2. What problems might an adult with a bilateral moderate high frequency sensorineural hearing loss have listening in background noise? How might hearing aids help? What are the limitations of hearing aids in this case?
3. Mrs Jones is a 72 year old retiree with a bilateral mild-moderate sensorineural hearing loss. She estimates that she has had this loss for around 12 years, and has not previously sought rehabilitation for it. She enjoys gardening and looks after her 3 grandchildren: Jasper (4 years old), Arabella (3 years old) and Cleo (1 year old); every Tuesday. She finds that she has trouble hearing Cleo when she wakes up from her nap, but does state that the house is very noisy when she looks after the children. Once a month she runs beginners gardening classes at her local community centre and will often have difficulty hearing questions from the audience. Understanding becomes especially hard when the students do practical work (re-potting etc).
a. Outline the elements that should form part of a rehabilitation program for a post-lingually deafened adult like Mrs Jones.
b. What listening goals might Mrs Jones choose and how will you address these? [10 marks]
4. Mr Phillips is a 45 year old bricklayer. He has a wife and no children. He sustained an injury at work that has led to hearing loss. You begin to test his hearing with Pure Tone Audiometry.

b. What is required to complete the audiogram? Be specific. [5 Marks]
