Abstract
The Desired Sensation Level (DSL) Method was originally developed in the early 1980s to provide clinicians with a systematic, science-based approach to pediatric hearing instrument fitting that ensures audibility of amplified speech by accounting for factors that are uniquely associated with the provision of amplification to infants and young children who have hearing loss. This review identifies and describes several of the primary factors that have been considered in the development of the DSL Method. Specifically, the issues discussed relate to: (1) the definition and measurement of relevant acoustic, electroacoustic and audiometric variables; (2) how the external ear acoustics of infants and young children are accounted for in the DSL Method for both audiometric assessment and in the fitting of amplification; and (3) how the DSL Method has evolved concurrently with developments in hearing instrument and electroacoustic measurement technologies. Finally, current issues in the field are identified that have motivated the development of version 5.0 of the DSL Method for hearing instrument fitting.
摘要
期望感觉级（DSL）方法最初是在20世纪80年代初开发的，旨在为临床医生提供一种系统的、基于科学的小儿听力仪器验配方法，该方法通过考虑与为听力损失的婴幼儿提供放大装置相关的独特因素，确保放大语音的可听度。本综述确定并描述了DSL方法开发过程中考虑的几个主要因素。具体而言，讨论的问题涉及：（1）相关声学、电声学和听力测量变量的定义和测量；（2）在DSL方法中，如何在听力评估和放大装置验配中考虑婴幼儿的外耳道声学特性；（3）DSL方法如何随着听力仪器和电声学测量技术的发展而同步演变。最后，确定了该领域目前的一些问题，这些问题推动了用于听力仪器验配的DSL方法5.0版的开发。
