Determining if maximum word-recognition scores (PBmax) are appropriate requires a confidence limit. This study established a 95% confidence limit for PBmax using NU-6 scores to assess hearing loss impact.

Area of Science:

  • Audiology
  • Speech-Language Pathology

Background:

  • Clinical decisions often hinge on the appropriateness of maximum word-recognition scores (PBmax) relative to sensorineural hearing loss.
  • Assessing if word recognition is poorer than expected necessitates understanding the lower boundary of PBmax for common speech tests.

Purpose of the Study:

  • To establish a confidence limit for PBmax using Northwestern University Test #6 (NU-6) scores.
  • To analyze PBmax in young and aged individuals with cochlear hearing loss.

Main Methods:

  • Collected word-recognition scores at various speech levels from 407 ears with diverse pure-tone averages.
  • Developed a computer simulation procedure to approximate the distribution of PBmax scores and determine the 95% confidence limit (CL).
  • Validated simulation results by comparing experimental and simulated PBmax data.

Main Results:

  • The 95% CL for PBmax was determined using NU-6 scores.
  • Young and aged subjects' scores falling outside the 95% CL corresponded to their sample proportions.
  • PBmax scores below the 95% CL indicate disproportionately poor word recognition relative to hearing loss degree.

Conclusions:

  • A 95% confidence limit for PBmax using NU-6 provides a benchmark for assessing word-recognition ability in relation to hearing loss.
  • Scores below this limit suggest word recognition may be poorer than expected.
  • Measuring word recognition at multiple levels is recommended if an initial score falls below the 95% CL to ensure an accurate PBmax estimate.
