指定数字接口设备的电气和机械要求，以允许通用控制设备（如台式计算机）连接到助听器，从而对其操作参数进行电气设置。 提供一个规范，使所有可由指定的数字接口设备编程的助听器都可以由单个控制设备和接口设备设置其参数。

Specifies the electrical and mechanical requirements for a digital interface device to allow a general-purpose control device such as a desktop computer to be connected to hearing aids, for the purpose of electrical setting of their operating parameters. Provides a specification such that all hearing aids which can be programmed by the specified digital interface device may have their parameters set by a single control device and interface device.
