Summary
The descending procedure and digit materials resulted in lower speech reception thresholds for normal-hearing individuals. This study compared different methods for measuring hearing ability.
Area of Science:
- Audiology
- Speech-Language Pathology
Background:
- Accurate measurement of speech reception thresholds (SRT) is crucial for diagnosing hearing loss.
- Standardized procedures and test materials are essential for reliable audiological assessments.
Purpose of the Study:
- To compare the effectiveness of ascending versus descending procedures for obtaining SRTs.
- To evaluate the impact of using digit versus spondee words as test materials on SRT measurements.
Main Methods:
- Thirty-two normal-hearing subjects participated in the study.
- Speech reception thresholds were measured using both ascending and descending procedures.
- Digit and spondee words were employed as test materials for threshold determination.
Main Results:
- The descending procedure yielded slightly lower (less Sound Pressure Level) speech thresholds compared to the ascending procedure for both digit and spondee materials.
- Digit materials generally resulted in lower threshold values than spondee words.
Conclusions:
- The descending procedure may offer an advantage in obtaining lower SRTs, potentially indicating greater sensitivity.
- Digit materials appear to be more efficient in yielding lower threshold values than spondee words in normal-hearing individuals.
