Detection and recognition masking-level differences for the individual CID W-1 spondaic words
Journal of Speech and Hearing Research
|June 1, 1982
Summary
This study determined masking-level differences for spondaic words in normal-hearing listeners. Results show significant differences, suggesting specific words can improve clinical speech masking-level difference assessments.
Area of Science:
- Audiology
- Psychoacoustics
- Speech Perception
Background:
- The masking-level difference (MLD) is crucial for understanding auditory processing.
- Standardized speech materials are needed to reliably measure MLDs in clinical settings.
Purpose of the Study:
- To establish detection and recognition masking-level differences for 36 CID W-1 spondaic words.
- To evaluate the clinical utility of MLDs for speech perception assessment.
Main Methods:
- 36 normal-hearing listeners participated.
- Speech-spectrum noise was used for masking under SoNo and S pi No conditions.
- Signal-to-noise ratios varied to determine detection and recognition thresholds.
Main Results:
- Mean MLD for detection was 9.4 dB; for recognition, it was 7.2 dB.
- Individual word recognition MLDs ranged from 4.4 dB to 10.0 dB.
- A list of 10 words with the largest MLDs was identified for potential clinical use.
Conclusions:
- The study provides normative MLD data for spondaic words.
- Specific spondaic words demonstrate greater MLDs, enhancing their potential for clinical application in speech audiometry.
