Lecture on Word Recognition Score Accuracy

Introduction

  • Speaker: Dr. Cliff Olson, Audiologist and founder of Applied Hearing Solutions.
  • Channel Focus: Hearing-related information for consumers.
  • Topic: Importance of word recognition score in hearing treatment.

Word Recognition Score (WRS)

  • Located in the speech testing section of an audiogram.
  • Indicates how well speech is understood in quiet conditions.
  • Provides a percentage correct score and volume level in decibels for each ear.
  • Two types:
    • Live speech
    • Recorded speech

Importance of Accurate Word Recognition Score

  • High accuracy indicates high probability of successful hearing aid treatment.
  • Low accuracy indicates lower success rate with hearing aids.
  • Critical for initial diagnosis and treatment planning.

Factors Affecting Word Recognition Score Accuracy

  1. Presentation Level

    • Must be fully audible, considering hearing loss to ensure accurate scores.
    • Incorrect levels lead to misinterpretation of hearing aid candidacy.
  2. Number of Words in the Test

    • Standard tests use lists with 50 words to minimize score variability.
    • Fewer words increase variability and reduce accuracy.
  3. Use of Recorded Words vs. Live Speech

    • Recorded words ensure consistency and reliability.
    • Live speech can lead to significant variability (up to 60% difference).
    • Clinical decisions should not be based on live speech scores.

Conclusion

  • Importance of best practices in audiologic testing.
  • Avoiding these errors ensures accurate diagnosis, realistic expectations, and proper treatment.
