规定了闭塞耳模拟器的声学性能。该设备设计用于 模拟耳模尖端和鼓膜之间耳道的声学行为， 包括成人中耳鼓膜的声阻抗。闭塞的耳朵 模拟器适用于对声载荷敏感的传感器。它也适合作为基础 用于模拟整个耳道和外耳（例如头部和躯干 模拟器）。描述了耳模拟器的具体物理实现。

The acoustical performance of an occluded ear simulator is specified. This device is designed to simulate the acoustical behavior of the ear canal between the tip of an ear mold and the eardrum, including the acoustic impedance at the eardrum of a median adult human ear. The occluded ear simulator is intended for transducers that are sensitive to acoustic load. It is also suitable as the basis for extensions intended to simulate the complete ear canal and the outer ear (e.g., head and torso simulators). Specific physical realizations of the ear simulator are described.
