The Adult EARS Test Battery is a new test that measures an adult's speech perceptual abilities with a cochlear
implant. The full test battery consists of open set (e.g. High Frequency and Low Frequency Word Identification)
and closed set (e.g. Consonant Identification, Vowel Identification) test materials. The High Frequency Word
Lists consists of one syllable words with CVC format where the consonants are all voiceless blends, stops or
fricatives and the vowels all have second formants above 1500 Hz. The Low Frequency Word Lists consists of
one syllable words with CVC format where the consonants are all voiced blends, glides, nasals or stops and the
vowels all have second formants below 1500 Hz. The High Frequency and Low Frequency Word Lists each have
two sub lists of 50 words, and these sub lists have been found to be reliable in a test-retest study completed at
Sunnybrook Health Sciences Centre. A cochlear implant user's responses to the High Frequency and Low
Frequency Word Lists can be analyzed to find error patterns that reflect the person's spectral resolution. This
information allows the clinician to better target auditory training as well as mapping to improve the listener's
spectral resolution in the problem frequency range. Case studies and examples will be presented, demonstrating
how the Adult EARS High Frequency and Low Frequency Word Lists can be used to diagnose problems with
spectral resolution.
