The following results were obtained, but with only fair reliability and considerable effort. Insert earphones were used.

NU-6 ½ lists

The above results were preliminarily obtained. The (m) following the spondee threshold indicates that contralateral masking was used.  The student recognized that masking was needed for air-conduction testing but the preceptor made the following points.

□       The interaural attenuation values are extremely and unbelievably high.  The sound should be crossing to the left ear at lower levels.

□       The child is difficult to test, but this raises question about whether the boy might be exaggerating the problems.

• What is the type and severity of the loss in the right ear?
• Contrast this to the stated “maximum conductive loss” level.  Do you understand why the preceptor audiologist is concerned?
