[The systematic selection of speech audiometric procedures].

BACKGROUND: The impact of hearing loss on the ability to participate in verbal communication can be directly quantified through the use of speech audiometry. Advances in technology and the associated reduction in background noise interference for hearing aids have allowed the reproduction of very complex acoustic environments, analogous to those in which conversations occur in daily life. These capabilities have led to the creation of numerous advanced speech audiometry measures, test procedures and environments, far beyond the presentation of isolated words in an otherwise noise-free testing booth.

OBJECTIVE: The aim of this study was to develop a set of systematic criteria for the appropriate selection of speech audiometric material, which are presented in this article in relationship to the most widely used test procedures.

RESULTS: Before an appropriate speech test can be selected from the numerous procedures available, the precise aims of the evaluation should be basically defined. Specific test characteristics, such as validity, objectivity, reliability and sensitivity are important for the selection of the correct test for the specific goals.

CONCLUSION: A concrete understanding of the goals of the evaluation as well as of specific test criteria play a crucial role in the selection of speech audiometry testing procedures.
