摘要：A method and apparatus (10) for objectively assessing acoustical performanceof an in-ear device (12) having a passageway (20) extending there through use a dualmicrophone probe (26) that removably engages the passageway (20). The acousticalperformance of the in-ear device (12) is performed with the in-ear device (12) insertedinto the ear canal (14) of the user and a reference sound source (24). A clip (36) holdingthe probe (26) in an acoustic near field of the sound source (24) permits real timecalibration 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, aswell as a protection test of the device (12) with an assessment of a filtered predictedexposure 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.
