Validation of the Adaptive Danish Sentence Test (DAST): Normative Data from a Template-Based, Linguistically Rich Sentence-in-Noise Test

/Objectives : This study describes the development and validation of the Danish Sentence Test (DAST), a Danish-language, adaptive speech-in-noise test constructed from a linguistically balanced corpus using a template-based method. This approach enables controlled linguistic variation while maintaining lexical consistency and may serve as a model for developing similar speech materials in other languages....

The DAST provides a validated, linguistically balanced speech-in-noise test with normative data for Danish-speaking populations — audiologists serving Danish-speaking patients should consider it for diagnostic and fitting verification purposes.

Robust, language-specific speech-in-noise tests with normative data are essential for accurate hearing assessment and hearing-aid fitting outcomes, and validated tools remain scarce for many languages.

1. 01DAST is a newly validated adaptive speech-in-noise test designed for Danish-speaking populations.
2. 02The test uses a template-based, linguistically rich sentence design to balance phonetic and semantic difficulty.
3. 03Normative data were collected from a representative Danish-speaking sample.
4. 04Adaptive test format improves efficiency and precision compared to fixed-level speech tests.
5. 05Fills a clinical gap for a psychometrically validated Danish speech-in-noise assessment tool.
