摘要： 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 in-field evaluation tests.

摘要： The present invention provides an apparatus (100) for determining in situ the acoustic seal provided by an in-ear device (10) of a hearing protection/aid nature inserted into the ear canal (20) of an individual. The device (10) having a sound bore (12) with an environment opening (13) and an ear opening (14) outside and inside the ear canal (20) respectively. The apparatus (100) includes a sound measurement device (41) that removably engages the environment opening (13), a probe microphone (42) and a reference microphone (44) isolated from each other and connected to a data processing unit (50) having a control box (52) and a speaker (51). Both microphones (42, 44) measure sound pressure levels (P3', P2') inside said ear canal (20) and outside in close proximity of the device (10) respectively, the sound pressure levels (P3' P2') corresponding to a known noise signal created by the speaker (51). The data processing unit (50) records and processes the sound pressure levels (P3', P2') to provide a corresponding calculated value of a sound pressure level difference provided by the device (10).
