The calibration and use of probe-test microphones

This paper examines the characteristics of the probe-tube microphone and its use in measuring sound pressure in the ear canal. Specifically the paper studies the free field and the coupler calibrations of several probe-tube microphones with tubes of different sizes and determines which characteristics of a probe tube are necessary for accurate measurements in both a free field and in a closed coupler.

Evaluating lexically controlled word lists for open set speech perception testing in profoundly hearing impaired children

This paper evaluates speech perception testing in pediatric cochlear implant users. Using pre-recorded stimulus presentation, the author replicated an earlier experiment comparing the Lexical Neighborhood List (LNT) test to the Phonetically Balanced Kindergarten (PB-K) test in estimating speech perception abilities in hearing impaired children.
