Audiologist frequently find that patients may benefit by wearing two hearing aids. If there is adequate residual hearing in both ears, the result is generally an improved ability to localize, or determine the location of, a source of sound. With good localization ability, patients are also able to hear a selected source in the presence of ambient noise (i.e., the "cocktail party effect"). As a result, prescription and purchase of two hearing aids is now common. However, no instrumentation is available to audiologists that would enable them to assess the ability of the client to localize sound sources either in aided or unaided conditions. As a result, localization ability is not considered in the fitting of hearing aids or in the assessment of auditory function. Such procedures are essential to ensure that the patient obtains the maximum possible benefit from binaural aids in light of the considerable additional cost and inconvenience of wearing and maintaining two hearing aids. The work on this grant project is aimed at the development of a compact device that will allow accurate measurement of localization ability to be made economically and quickly. The theory of the method to be used has been evaluated experimentally during Phase I. In Phase II, a practical device is to be designed, thoroughly tested, and refined in clinical use.

听力学家经常发现，患者可能会受益于佩戴两个 助听器. 如果双耳都有足够的残余听力， 结果通常是提高了定位或确定 声音的来源，声音的来源。 具有良好的本地化能力， 患者还能够在存在 环境噪声（即，“鸡尾酒会效应”（cocktail party effect）。 因此，现在处方和购买两种助听器是 共同 然而，没有仪器可用于听力学家， 使他们能够评估客户的本地化能力， 在辅助或无辅助条件下的声源。 因此，在本发明中， 助听器验配中不考虑定位能力 或在听觉功能的评估中。 如此类程序并 确保患者获得最大可能的 受益于双耳助听器， 助听器的选配和保养 这项赠款项目的工作旨在开发一种 紧凑的设备，将允许精确测量定位 能够经济快速地制造。 量法的基本概念 已在第一阶段进行了实验评估。 同相 第二，设计一个实用的装置，进行彻底的测试， 在临床使用中得到改善。
