Introduction

• 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.
