Measuring Audiometric Outcomes
Audiometry provides evidence to 19 of the topic areas in this book and to much of the otolaryngologic literature. Audiometric evaluations, consisting of pure tone thresholds and word recognition scores are not data points; they are very general evaluations designed to cover all reasonable questions about the peripheral auditory system of the patient. It is clear that audiometric evaluations contain a great deal of useful data, and equally clear that large amounts of the information should be reduced and refocused in order to serve as useful study evidence. This chapter will explore some fine points regarding audiometric data, and attempt to provide support for the process of data reduction and focus. Issues related to pure tones will be addressed first, followed by a discussion of standard word recognition.
