Imagine you are given the following two audiograms (upper panels) and the speech discrimination results (lower panel: the ability to understand speech as a function of the loudness of that speech). FREQUENCY (Hertz) decibel HEARING LOSS 2 30 60 2 30 FREQUENCY (Hertz) 150 500 1000 2000 4000 8000 BONE Audiogram A 100 Normative data. SPEECH COMPREHENSION (%) 00 9 40 20 ' 20 + AIR decibel HEARING LOSS -10 2 40 30 Speech result 1 40 250 500 1000 3000 4000 6000 8000 Audiogram B /Speech result 2 60 80 SPEECH INTENSITY (dB Sound Pressure Level) AIR BONE From these data, predict answers to the following questions: 1. Where is the most likely site of hearing loss suffered by the patient with Audiogram A? (Circle the correct answer) (a) Cochlear hearing loss (b) Middle ear hearing loss (c) Mixed cochlear + middle ear hearing loss 2. Where is the most likely site of hearing loss suffered by the patient with Audiogram BA? (Circle the correct answer) (a) Cochlear hearing loss (b) Middle ear hearing loss (c) Mixed cochlear + middle ear hearing loss 3. In the speech discrimination test results in the lower figure, which Speech Result curve is likely to be that for the person with Audiogram A and which for the person with Audiogram A? Patient A: Speech Result Patient B: Speech Result
