    • A method and apparatus (10) for objectively assessing acoustical performance of an in-ear device (12) having a passageway (20) extending there through use a dual microphone probe (26) that removably engages the passageway (20). The acoustical performance of the in-ear device (12) is performed with the in-ear device (12) inserted into the ear canal (14) of the user and a reference sound source (24). A clip (36) holding the probe (26) in an acoustic near field of the sound source (24) permits real time calibration thereof. The method and apparatus (10) allow on-site and in-situ measurement of a predicted personal attenuation rating (P-PAR) of the device, a subject-fit re-insertion test, an acoustic seal test, a rating test, a stability and reliability test, as well as a protection test of the device (12) with an assessment of a filtered predicted exposure level (F-PEL) at the ear for a specific noise exposure level. The apparatus (10) may be simply housed along with the sound source (24) for the in-field evaluation tests.
    • 的方法和设备(10),用于客观assesing具有通道(20),耳内设备(12)的声学性能通过使用延伸有一个双麦克风探针(26)做了可拆卸接合通路(20)。 耳内设备(12)的声学性能进行与插入所述用户和参考声源(24)的耳道(14)的耳内设备(12)。 保持样品(26)声学声源(24)的近场的夹子(36),允许它们的实时校准。 该方法和装置(10)允许在现场和原位预测个人衰减等级的装置的(P-PAR),声学密封试验的受试者配合重新插入了测试,等级测试,测定用 具有稳定性和可靠性测试,以及该装置(12)的保护测试在耳朵处针对特定噪声暴露水平滤波后预测的暴露水平(PEL F)的评估。 的装置(10)可以简单地坐落地连同声源(24),用于在所述视场的评价试验。
