Development of a novel Italian speech-in-noise test using a roving-level adaptive method: adult population-based...

Area of Science:

• Audiology
• Speech-language pathology
• Hearing science

Background:

• Standard hearing evaluations (pure-tone audiometry, word lists in quiet) are insufficient for real-world conditions.
• Advancements in hearing devices necessitate more realistic functional hearing assessments.
• Existing speech-in-noise tests are limited in scope and availability.

Purpose of the Study:

• To develop and validate a novel roving-level adaptive speech-in-noise test.
• To establish normative data for this test in healthy Italian adults.
• To provide a more ecologically valid method for assessing speech recognition in noise.

Main Methods:

• A roving-level adaptive speech-in-noise test was designed.
• The test involved target and competing speech signals with varying levels.
• Data were collected from healthy Italian adult participants.

Main Results:

• New normative data were generated for the Italian language population.
• The developed test effectively simulates complex auditory environments.
• The study provides a foundation for future clinical applications.

Conclusions:

• The roving-level adaptive speech-in-noise test offers a more realistic assessment of hearing function compared to traditional methods.
• This test is valuable for evaluating the performance of hearing devices.
• Normative data are crucial for accurate interpretation of speech-in-noise test results in Italian speakers.
